Terms of Service

Terms of Service

The rules that govern your use of WriteHuman's platform and services.

Last updated: September 21, 2026

These Terms of Service (the “Terms”) are a legally binding agreement between you and Write Human LLC, located at 1224 Shirlton Rd, Midlothian, VA 23114, United States (“WriteHuman,” “we,” “us,” or “our”). Section 26 contains a binding arbitration agreement and a waiver of class actions and jury trials.

These Terms govern your access to and use of: the website at writehuman.ai and its subdomains (the “Site”); the WriteHuman mobile apps for iOS and Android (the “Apps”); the WriteHuman browser extension (the “Extension”); the WriteHuman developer API at api.writehuman.ai (the “API”) and the WriteHuman Model Context Protocol server (the “MCP Server,” and together with the API, the “Developer Services”); and every related tool, feature, and service we offer (all together, the “Services”). “You” means you, the person using the Services, and if you use them on behalf of an organization, that organization too.

You can print or save a copy of these Terms for your records.

Table of Contents

1. Agreement to These Terms

You accept these Terms when you do any of the following: create an account (including by signing up with Google or Apple); click, tap, or check anything that says you agree to these Terms or that by continuing you agree to them; buy a paid plan, top-up, or other product; or access or use any part of the Services, with or without an account. If you do not agree to these Terms, do not use the Services.

These Terms include any plan details, offer terms, or other terms we show you when you buy something or use a particular feature. Our Privacy Policy and Cookie Policy explain how we handle personal information and use cookies. They are notices, not part of this contract, except where these Terms expressly refer to them to define or limit a right (for example, in Sections 8 and 17). If you accept these Terms on behalf of an organization, you confirm that you have authority to bind it.

2. Changes to These Terms

We may revise and update these Terms at any time. When we do, we will post the updated Terms on this page and update the “Last updated” date. Changes take effect when we post them, unless we say otherwise. If you continue to use the Services after changes are posted, you accept the updated Terms. You are responsible for checking this page so you are aware of any changes. We may choose to give you additional notice of a change, but we are not required to.

If we change Section 26 (Dispute Resolution and Binding Arbitration) after you have accepted it, the change does not apply to any Dispute (as defined in Section 26) that arose before the change was posted.

3. Eligibility

You must be at least 18 years old to use the Services. By using the Services, you confirm that you are 18 or older, that you can form a binding contract, that you are not barred from using the Services under the laws that apply to you, and that we have not previously suspended or terminated your access to the Services.

4. Your Account

Registration.

Some features require an account. You must give us accurate and complete information and keep it up to date. You can sign up with an email address and password or through a sign-in provider such as Google or Apple.

One person per account. No sharing.

Each account is for one person only. No one else may use your account, your password, or your sign-in session. If more than one person needs the Services, each person needs their own account and, for paid features, their own subscription. You are responsible for everything that happens under your account, and you must tell us right away at support@writehuman.ai if you believe someone else has accessed it.

Session and location limits.

To protect the Services, we monitor how accounts are used, including the number of devices and sessions signed in at the same time and the IP addresses and locations they come from. We may limit how many sessions can be signed in at once, ask you to end a session or automatically sign out older sessions when you reach that limit, and sign out every session on an account (and require you to sign in again) when the account is used from an unusual number of locations or networks in a short time. If we believe an account is being shared, pooled, resold, rented, or used through a proxy or relay service, we may restrict, suspend, or terminate it without notice and without a refund.

Using the Services without an account.

Some tools can be used without signing in. These Terms still apply when you do. We may apply usage limits to signed-out use by device, browser, and IP address.

5. The Services

WriteHuman provides AI-assisted writing tools, including an AI humanizer that rewrites text so it reads more naturally, an AI text detector, an AI image detector, grammar and writing suggestions, submission history, and related tools. We offer them through the Site, the Apps, the Extension, and the Developer Services. The Services use our own AI models and may also use AI models and services from third-party providers.

No guaranteed outcomes.

AI outputs and AI detection results are probabilistic and can be wrong. We do not guarantee that any text you create, humanize, or edit with the Services will receive any particular score, label, or result from any AI detection tool, including ours. Detection results, whether from us or anyone else, are estimates. They are not proof of who or what wrote a piece of text, and you must not use them as the only basis for a decision about a person, such as an employment or disciplinary decision. Outputs may be inaccurate, incomplete, or change the meaning of your text, and you are responsible for reviewing them before you use them.

Content moderation.

We may use automated systems to screen requests, and we may decline to process a request, or limit an account, if content is flagged by those systems or appears to violate these Terms.

Changes to the Services.

We may add, change, limit, or remove any feature, tool, model, plan, or part of the Services at any time, with or without notice. Features labeled as beta, preview, or experimental may be less reliable and may change or be removed at any time. We do not promise that the Services will always be available or free of errors, and we have no obligation to support, maintain, or update any part of them.

Where the Services are offered.

We operate the Services from the United States. If you use them from another country, you are responsible for complying with the laws that apply to you there.

6. Our Intellectual Property and Your License

The Services, including our software, models, algorithms, databases, designs, text, graphics, logos, and the WriteHuman name and trademarks, are owned by us or our licensors and are protected by intellectual property laws. Except for the limited license below, these Terms do not give you any right, title, or interest in the Services, and we reserve all rights not expressly granted.

Subject to these Terms, including your payment of any applicable fees, we grant you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to access and use the Services for your own personal purposes or for the internal business purposes of the organization you represent. Additional license terms for the Apps, the Extension, and the Developer Services are in Sections 16, 17, and 18. Commercial integration of the Services into your own products is permitted only through the Developer Services under Section 18.

Your rights in the text you submit and in your Outputs are described in Sections 8 and 9.

7. Prohibited Activities

You may not use the Services, or help or allow anyone else to use them, to do any of the following:

  • Engage in academic dishonesty or help others do so, or submit work that breaks any rule on AI use or authorship that applies to you, such as a rule set by an employer, publisher, or platform.
  • Create, edit, or distribute content that is unlawful, defamatory, fraudulent, deceptive, harassing, hateful, sexually exploitative of anyone, or that infringes or violates anyone's intellectual property, privacy, publicity, or other rights.
  • Create fake reviews or testimonials, impersonate any person or organization, run phishing or other scams, spread disinformation, or pass off content as human-written where the law requires you to disclose that AI was used.
  • Submit any content that sexualizes minors, or use the Services in any way that harms or endangers minors.
  • Resell, rent, lease, sublicense, or share access to the Services or to any account, including by operating a proxy, relay, wrapper, pooled-account, or credential-sharing service. The only exception is integration through the Developer Services as Section 18 permits.
  • Access or use the Site, the Apps, or the Extension through bots, scripts, crawlers, scrapers, headless browsers, or any other automated means. Automated access is allowed only through the Developer Services with valid credentials under Section 18.
  • Scrape, crawl, or systematically collect data, content, or outputs from the Services, or compile them into a database, dataset, or directory.
  • Copy, modify, decompile, disassemble, or reverse engineer any part of the Services or their software or models, or try to extract model weights, prompts, training data, or source code, except where the law expressly allows it despite this restriction.
  • Use the Services, or any outputs or data from them, to build, train, or improve a product or model that competes with the Services.
  • Circumvent, disable, or interfere with any usage limit, free plan limit, rate limit, paywall, content moderation, security feature, or access restriction, including by using multiple accounts, VPNs, proxies, device resets, or cleared cookies to get more free usage or to avoid a suspension.
  • Create more than one free account, or obtain referral credits, promotional offers, or trials through fake, duplicate, or self-referred accounts.
  • Upload viruses, malware, or other harmful code, or anything that collects information from or about other users.
  • Interfere with, disrupt, overload, or place an unreasonable burden on the Services or the networks and systems connected to them, or try to gain unauthorized access to any of them.
  • Frame or mirror the Services, or remove or alter any proprietary notices.
  • Use another person's account or credentials, or misrepresent your identity or your connection with any person or organization.
  • Harass, threaten, or abuse our employees, contractors, or other users, or submit false reports to our support team.
  • Make a false chargeback claim or otherwise commit payment fraud.
  • Violate any law or regulation, or any of these Terms.

We may investigate and take any action we consider appropriate if we believe you have violated this section, including removing content, declining requests, restricting features, suspending or terminating your account without a refund, and reporting you to law enforcement. We may cooperate with law enforcement and with court orders, including by disclosing information about you. You release us from any claims arising from actions we take in good faith during or as a result of such an investigation.

8. Your Content and How We Use It

What “Your Content” means.

“Input” means the text, images, files, and other material you submit to the Services, whether you wrote it yourself or it was generated by another AI tool. “Outputs” means the results the Services generate from your Input, including humanized text, suggestions, and detection scores, and including any additional versions we generate from your Input but do not show you. “Your Content” means your Input, your Outputs, and any feedback, ratings, or other responses you give us about them.

You keep ownership of your Input.

As between you and us, you keep whatever ownership rights you have in your Input. Your rights in Outputs are described in Section 9.

The license you give us.

You grant us, our affiliates, and our successors a worldwide, non-exclusive, royalty-free, fully paid, perpetual, irrevocable, and transferable license, with the right to sublicense to our service providers, contractors, and affiliates through multiple tiers, to host, store, copy, reproduce, process, analyze, transmit, display, modify, adapt, translate, create derivative works from, and otherwise use Your Content in order to:

  • provide, operate, maintain, secure, and support the Services;
  • develop, train, evaluate, test, and improve our AI models and our other products and services;
  • prevent fraud and abuse, enforce these Terms, and comply with the law; and
  • do anything else described in our Privacy Policy.

We use your content to train our models.

We use Your Content to train, evaluate, and improve our AI models. This includes the text you submit to our humanizer and AI detector on the Site, in the Apps, and through the Extension, the results we return, the additional versions we generate but do not show you, and your feedback and ratings, as described in our Privacy Policy. This use is part of how the Services work, and there is no setting to exclude your content from it. People working for us may review Your Content for these purposes. Because this license is irrevocable, it continues after you delete content from your history, cancel your plan, or delete your account: we may keep and use copies already included in training or evaluation data, and models already trained on them are not changed. Do not submit anything you are not allowed to share with us or that you do not want used this way. Any rights you have under privacy laws are described in our Privacy Policy, and nothing in these Terms limits rights under those laws that cannot be limited by contract.

Exceptions. The training use described above does not apply to text you submit through the Developer Services (see Section 18). For the Extension, our use of the data it collects is also limited as described in the Chrome extension section of our Privacy Policy and by the Chrome Web Store User Data Policy, and those limits control if they conflict with this section.

Your responsibilities for Your Content.

You are solely responsible for Your Content. You confirm that you own or have all the rights, licenses, and permissions needed to submit your Input and to grant the license above, and that your Input and your use of it do not violate these Terms, any law, or anyone's rights. Do not submit sensitive personal information (such as health, financial, or government ID information) or other people's personal information unless you have the right to do so. We do not have to store, keep, or return Your Content, and you should keep your own copies of anything important.

Public content.

If you post content publicly through the Services or about us in a place we host, such as a comment or review, the license above also lets us display, publish, and distribute that content in any media, and you waive any moral rights in it to the extent the law allows.

9. Outputs

As between you and us, and to the extent we have any rights in them, we assign to you our rights in the Outputs we deliver to you, subject to your compliance with these Terms and to the license you grant us in Section 8. You may use those Outputs for any lawful purpose, including commercial purposes, that does not violate these Terms.

Because of how AI works, other users may receive Outputs that are the same as or similar to yours, and those Outputs are not yours. We make no promise that any Output is original, accurate, free of errors, protectable by copyright, or free from third-party rights. You are responsible for reviewing Outputs before you rely on, publish, or submit them, and for meeting any obligation you have to disclose your use of AI.

10. Feedback

If you send us ideas, suggestions, bug reports, survey answers, ratings, reviews, or other feedback about the Services (“Feedback”), you grant us a worldwide, perpetual, irrevocable, royalty-free, fully paid, transferable, and sublicensable license to use, copy, modify, publish, and otherwise exploit that Feedback for any purpose, without any obligation or payment to you.

12. Plan Changes, Cancellation, and Refunds

Upgrades and downgrades on the Site.

You can change your Site plan at any time from the Site. Plan changes take effect right away.

  • Upgrades. When you move to a higher-priced plan, we immediately charge the prorated difference for the rest of your current billing period. If that payment does not go through, your plan is not changed.
  • Downgrades. When you move to a lower-priced plan, you switch right away, and the unused time on your old plan is credited to your account balance and applied to your future invoices. That credit is not refundable in cash.
  • Changing billing period. Switching between monthly and annual billing is treated the same way, and your new billing period may start on the date of the switch.
  • Discounts. If your subscription has a discount, we may adjust or remove it when you change plans.

Plan changes for Developer API plans work differently, as described in Section 18.

Pausing.

We may offer you the option to pause a subscription for a set period. Once a pause takes effect, you are not charged, and your paid features are unavailable until the pause ends. Some tools may be unavailable entirely while your subscription is paused. Billing and your paid plan resume automatically on the resume date shown, unless you cancel before then. If you resume early or change plans while paused, the pause ends right away and billing restarts.

How to cancel.

  • Site plans: cancel online at any time in My Account.
  • Developer API plans: cancel online at any time from your developer dashboard.
  • App subscriptions: cancel in your Apple ID or Google Play subscription settings (see Section 16). We cannot cancel these for you.

When you cancel a subscription we bill through Stripe, the cancellation takes effect at the end of your current billing period. You keep access to your paid plan until then, and after that your account moves to the free plan. You can reactivate before the period ends to keep your subscription. Uninstalling an App or the Extension, or simply not using the Services, does not cancel a subscription.

Refunds.

All payments are non-refundable except where the law requires a refund. We do not give refunds or credits for partial billing periods, unused time, unused words, requests, credits, or top-ups, plan downgrades (other than the account credit described above), suspension or termination of your account, or periods in which you did not use the Services. If we choose to give a refund or credit in a particular case, that does not require us to do so again. Refunds for App Store and Google Play purchases are handled only by Apple and Google under their policies.

Deleting your account.

You can delete your account at any time in My Account on the Site, or by contacting us. When you delete your account:

  • we cancel, right away, every subscription we bill through Stripe, including Site plans and Developer API plans, whatever their status (for example active, paused, or past due). You lose any time left in the current billing period, and it is not refunded;
  • any subscription you bought through the App Store or Google Play is not cancelled. You must cancel it yourself in your store account settings, preferably before you delete your account, or you will keep being charged by Apple or Google;
  • any unused words, credits, and top-up balances are forfeited; and
  • we may keep some information after your account is deleted, as described in our Privacy Policy, and the license in Section 8 continues.

13. Free Plans, Usage Limits, and Promotions

Free plans.

We may offer free access to some Services with limited usage. We may change the limits, features, or availability of free access, or end it, at any time and without notice. We may enforce free limits per account, device, browser, and IP address.

Usage limits on every plan.

Every plan, free or paid, is subject to limits, which may include limits on words per request, requests or words per month or other usage period, requests per minute, and the number of results per request. Limits are shown in the Services or in your plan details, and we may change them. Unused allowances do not roll over to the next period unless we say otherwise.

“Unlimited” plans and fair use.

Some plans or features are described as “Unlimited” (for example, on our Ultra plan). “Unlimited” means the plan has no stated monthly allowance for that feature. It does not mean there are no limits. Every plan described as “Unlimited” still has monthly caps on the number of requests (which may differ by tool), per-request word limits, and rate limits. We set these caps at levels we expect to be above what ordinary personal use needs, we may change them, and we enforce them automatically. Once you reach a cap, further requests may be refused until the cap resets for your next usage period. We may also throttle, restrict, or suspend use that goes beyond the fair use limits we set to protect the Services and other users, or that indicates automation, account sharing, resale, or any other use these Terms prohibit.

Promotions, discounts, and trials.

We may offer discount codes, promotional prices, bonus credits, free trials, or other offers. Each offer is subject to the terms shown with it and to these Terms. Unless the offer says otherwise, an offer is limited to one per person, cannot be combined with other offers, has no cash value, cannot be transferred, and applies only for the period stated. When a promotional period ends, your subscription renews at the regular price. If an offer includes a free trial or introductory price, it will show when the trial or introductory period ends and the price you will be charged after that, and you will be charged that price unless you cancel before the trial or introductory period ends. We may change or end any offer at any time, and we may cancel offers or credits obtained through fraud, abuse, or a breach of these Terms.

14. Referral Credits

We may let you invite others to WriteHuman with a referral link and earn bonus credits when the people you invite sign up and use the Services, and we may give bonus credits to people who join through a referral link. The rules shown in the Services at the time, including how credits are earned, how many you can earn, and when they expire, apply.

  • Referral credits are bonus usage for the Services. They have no cash value, cannot be sold, transferred, or exchanged for money, and expire as shown in the Services.
  • Each person, account, and device can receive an invitee bonus only once. Referring yourself, or using duplicate accounts, shared devices, or fake identities to earn credits, is not allowed.
  • We review referrals for fraud, including by comparing device and account information. We may withhold, void, or remove referral credits, and suspend or terminate accounts, if we believe the program has been abused or these Terms have been violated.
  • You may not advertise your referral link in spam, in paid search ads that use our name or trademarks, or in any misleading way.
  • We may change the referral program, its rewards, or its rules, or end it, at any time. Unused credits may be removed when the program ends.

15. Affiliate Program

If you join the WriteHuman affiliate program, your participation is governed by the separate affiliate agreement you accept when you sign up for the program through our affiliate platform. See our Affiliates page for more information. These Terms continue to govern your use of the Services. If the affiliate agreement and these Terms conflict about the affiliate program, the affiliate agreement controls.

16. Mobile Apps

License.

Subject to these Terms, we grant you a limited, non-exclusive, non-transferable, revocable license to install and use the Apps on devices you own or control, for your personal use, and only as allowed by the usage rules of the app store you got the App from. For the iOS App, that includes Apple's Usage Rules in the App Store Terms of Service, which may allow the App to be accessed by other accounts in your Family Sharing group.

In-app subscriptions.

Subscriptions you buy in the Apps are sold, billed, and renewed by Apple or Google, not by us. Payment is charged to your Apple ID or Google Play account when you confirm the purchase. Your subscription renews automatically for the same billing period (weekly or monthly, as shown when you buy) unless you turn off auto-renew. For the App Store, you must turn off auto-renew at least 24 hours before the end of the current period, and Apple charges your account for renewal within the 24 hours before the current period ends. Google Play's timing is set by Google. You can manage and cancel your subscription in your Apple ID or Google Play subscription settings. Deleting the App or deleting your WriteHuman account does not cancel an app store subscription. Refunds for these purchases are handled only by Apple or Google under their policies, and we cannot issue them. If these Terms conflict with the app store's terms about billing or refunds for an in-app purchase, the app store's terms control.

Permissions and notifications.

The Apps may ask for permissions, such as permission to send push notifications or, on iOS, permission to track. You can change these choices at any time in your device settings or in the App. Our Privacy Policy explains how the Apps handle your information.

Apple App Store.

If you downloaded an App from Apple's App Store, your license to use the App is also subject to Apple's Licensed Application End User License Agreement (unless we provide a custom license agreement through the App Store), and these Terms govern your account, your use of the Services through the App, and your relationship with us. If they conflict, these Terms control except where Apple's agreement or the App Store rules require otherwise. You and we also agree that:

  • these Terms are between you and Write Human LLC only, not Apple Inc. (“Apple”), and we, not Apple, are solely responsible for the App and its content;
  • your license to the App is limited to a non-transferable license to use it on Apple-branded products that you own or control, as permitted by the Usage Rules in the App Store Terms of Service;
  • Apple has no obligation to provide any maintenance or support services for the App;
  • if the App fails to conform to any applicable warranty, you may notify Apple and Apple will refund the purchase price of the App (if any) to you; to the maximum extent the law allows, Apple has no other warranty obligation for the App, and any other claims, losses, liabilities, damages, costs, or expenses caused by a failure to conform to a warranty are our responsibility to the extent these Terms do not disclaim them;
  • we, not Apple, are responsible for addressing any claims by you or a third party relating to the App or your possession or use of it, including product liability claims, claims that the App fails to meet any legal or regulatory requirement, and claims under consumer protection, privacy, or similar laws;
  • if a third party claims that the App or your possession or use of it infringes that third party's intellectual property rights, we, not Apple, are responsible for the investigation, defense, settlement, and discharge of that claim to the extent these Terms require;
  • you confirm that you are not located in a country subject to a U.S. Government embargo or designated by the U.S. Government as a “terrorist supporting” country, and that you are not on any U.S. Government list of prohibited or restricted parties;
  • questions, complaints, and claims about the App should be sent to us using the contact details in Section 29;
  • you must comply with any applicable third-party terms, such as your wireless data service agreement, when using the App; and
  • Apple and its subsidiaries are third-party beneficiaries of these Terms as they relate to your license of the App, and once you accept these Terms, Apple will have the right (and will be deemed to have accepted the right) to enforce them against you as a third-party beneficiary.

Google Play.

If you downloaded an App from Google Play, your use of the App is also subject to the Google Play Terms of Service. Google is not a party to these Terms and is not responsible for the App.

17. Chrome Extension

This section applies to the WriteHuman extension for Google Chrome and other Chromium-based browsers.

License.

Subject to these Terms, we grant you a limited, non-exclusive, non-transferable, revocable license to install and use the Extension for your personal use or your own internal business use. Your use of the Extension is also subject to the terms of the Chrome Web Store.

How the Extension works.

The Extension sends the text in the writing field you are actively editing (including before you sign in), and any text you choose to humanize or check, to our servers for processing, and saves humanizer and AI detector results to your history. Extension features are subject to your plan's limits. The Chrome extension section of our Privacy Policy describes what it collects and how we use, store, and share it, and our use of that information adheres to the Chrome Web Store User Data Policy, including its Limited Use requirements.

Your responsibilities.

You can pause the Extension or turn it off for individual sites at any time. You are responsible for deciding where to use the Extension and for making sure that your use of it on any website, app, or system (for example, your employer's systems or a third-party service) complies with that site's terms and with your obligations to others, including any duty to keep information confidential. You are responsible for any suggestion you accept.

Updates and availability.

The Extension may update automatically. It may not work on every website or editor, and we may change or discontinue it at any time.

18. Developer API and MCP Server

This section applies to the Developer Services (the API at api.writehuman.ai and the MCP Server). It adds to the rest of these Terms and controls if it conflicts with another section about them.

Access.

To use the API, you need a WriteHuman account and an active API subscription. The MCP Server is available to accounts on a plan that includes MCP access (currently our Pro and Ultra plans) and to accounts with an active API subscription. Documentation is available in our API documentation and on our MCP page. An API subscription is separate from any Site plan, and each is billed and cancelled separately.

API keys and security.

You are responsible for keeping your API keys and MCP access tokens secret and for all activity that uses them, including unauthorized activity until you revoke them. Use API keys only from servers you control. Do not put them in client-side code, mobile apps, browser extensions, or public code repositories, and do not share them with anyone outside your organization. You can create and revoke keys from your developer dashboard, and you must revoke any key right away if you believe it has been exposed. We may revoke or suspend any key or token that we believe is compromised or is being misused.

Plans and included words.

Each API plan includes a number of words for each monthly billing period, as shown when you buy it. Your included words reset at the start of each billing period, and unused included words do not roll over. Each plan also has a maximum number of words per request and limits on request rates.

Word metering.

We measure API usage in words, based on the input text you submit, not the output. Humanization and AI detection requests both count against your words. Words are counted by our systems when the request is made. For some languages (for example Chinese, Japanese, and Vietnamese), and for any text whose length in characters is high compared with the number of spaces in it (for example text without spaces, or with long words, links, or code), we estimate the word count from the number of characters or by another method, and we bill that estimate. Our count is final and controls over any count you make yourself. We do not make retroactive adjustments, credits, or refunds for usage, including usage caused by errors or loops in your code or by anyone using your keys.

Top-up words.

  • You can buy top-up word packs only while you have an active API subscription, and you can use top-up words only while you have an active API subscription, including when you use them through the MCP Server.
  • Top-up words are used only after the included words for your current billing period run out.
  • Top-up words do not expire. If your API subscription ends, your unused top-up words stay on your account but cannot be used until you have an active API subscription again.
  • Your unused top-up balance cannot exceed a maximum we set (currently 1,000,000 words).
  • Top-ups are non-refundable, have no cash value, cannot be transferred, and are forfeited if your account is deleted or terminated for any reason.

MCP usage.

Plans that include MCP access let you make MCP requests up to your plan's limits for each billing period. Depending on the plan, MCP requests have their own allowance or share your plan's regular allowance, as shown in your plan details. Once that allowance runs out, MCP requests may use your API plan's included words and then your top-up words, but only while you have an active API subscription. MCP requests are also subject to per-request word limits and rate limits. The MCP Server is for your own use through AI clients you control. It may not be connected to shared connectors, multi-user bots, or team accounts; use the API for those.

Rate limits and fair use.

We set rate, concurrency, and per-request limits for the Developer Services and may change them at any time. Requests over a limit, or made when you have no words or requests left, may be delayed, queued, or rejected, and we may throttle or suspend use that places an unreasonable load on the Developer Services.

What you may build.

Subject to these Terms and an active subscription, we grant you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to use the API to integrate WriteHuman humanization and AI detection into your own websites, applications, products, services, and internal workflows, including commercial ones. You may present results to your own users under your own brand, and you do not have to name WriteHuman, as long as you do not suggest that we endorse your product. You may not use our name, logos, or trademarks, except to say accurately that your product uses WriteHuman.

What you may not do with the Developer Services.

  • Resell, sublicense, or provide raw access to the Developer Services, including by offering an API, SDK, or interface whose main purpose is to give others access to our Developer Services. Your product must add meaningful functionality of its own.
  • Use the Developer Services, their outputs, or any data from them to build, train, or improve a humanization, AI detection, or other product or model that competes with the Services, or to create a dataset for that purpose.
  • Use, or let your end users use, the Developer Services for anything Section 7 prohibits, including offering services that help others engage in academic dishonesty.
  • Use detection results, or let your end users use them, as the only basis for a decision that has legal or similarly significant effects on a person, such as a hiring, employment, or disciplinary decision. If your product shows detection results to others, you must tell them that the results are estimates that can be wrong.

Your end users.

If you let others use the Developer Services through your product, you are responsible for them and for their use. You must: have all the rights and permissions needed to submit their content to us; give them any notices and get any consents the law requires, including notice that their content is processed by third-party AI services; have terms and a privacy policy for your product that are at least as protective of us as these Terms; comply with all privacy, data protection, and consumer protection laws that apply to you; and provide support to them yourself. You must not knowingly submit content from, or allow use by, children under 13, or anyone under 18 where the law requires consent or other steps you have not taken. We have no obligations to your end users.

Data handling.

We use the text you submit through the Developer Services, and the results, only to return your results, screen for abuse and safety, and check that new versions of our models work reliably. We do not store them in our databases (our service logs may record model-check results temporarily during limited testing periods) or use them to train our models, so the training use in Section 8 does not apply. We keep request metadata, such as time, endpoint or tool, word counts, status, response time, key or client, and IP address, for billing, security, abuse prevention, and support. Where your text includes personal information about other people, we process it on your behalf as your service provider (and, where the GDPR or UK GDPR applies, your processor) only for these purposes, using the service providers described in our Privacy Policy under contracts that limit their use, and we do not sell or share it or combine it with other information except as the law allows service providers to do. You are responsible for having a lawful basis to send it. If the law requires a data processing agreement, contact support@writehuman.ai before you send that information.

Regulated data.

Do not submit protected health information under HIPAA, payment card data, government ID numbers, or other data that requires special security or contractual terms, unless we have agreed to it in writing.

MCP connected apps.

When you connect an AI client, such as an AI assistant or code editor, to your account through the MCP Server, you authorize that client to call WriteHuman tools on your behalf and to use your plan's allowances. The text you send through that client is also shared with, and processed by, the client's provider under its own terms and privacy policy, and we are not responsible for it. You are responsible for the clients you connect. To disconnect, remove WriteHuman in your AI client's connector settings. To make sure access is revoked on our side, contact us at support@writehuman.ai. We may revoke any MCP connection at any time.

Changes and deprecation.

We may change, add, deprecate, or remove endpoints, tools, parameters, models, response formats, and limits at any time, with or without notice.

No service level commitment.

Unless we have signed a separate written agreement with you, the Developer Services are provided without any commitment on uptime, availability, response time, throughput, or support. Any response times we publish are estimates.

Billing, plan changes, and failed payments.

API plans are billed monthly in advance through Stripe and renew automatically, and failed payments are handled as described in Section 11, except that API access may stop right away until the payment succeeds. Upgrades work like Site upgrades in Section 12 and also cancel any scheduled cancellation. Downgrades take effect right away with no credit or refund for the unused part of the higher plan, and words already used in the current billing period count toward the new plan's allowance. You can cancel from your developer dashboard, effective at the end of the current billing period.

Suspension and termination.

When your access to the Developer Services ends, you must stop using them and delete your keys. Suspension and termination are covered by Section 21, and your remaining words and top-ups are handled as described above.

19. Third-Party Services and Links

The Services may link to, or work with, services we do not control, such as Stripe, the App Store and Google Play, sign-in providers such as Google and Apple, web browsers and browser stores, AI clients you connect through the MCP Server, and other websites. Your use of those services is governed by their own terms and privacy policies. We are not responsible for them, for their content, availability, or security, or for any loss or damage caused by your use of them, and a link does not mean we endorse them.

20. Privacy

Our Privacy Policy explains how we collect, use, and share personal information, and our Cookie Policy explains how we use cookies and similar technologies. You can make choices about the use of your information for advertising on our Your Privacy Choices page.

21. Suspension and Termination

We may suspend or terminate your account, or your access to all or part of the Services, at any time, with or without notice, including while we investigate, if we believe you have violated these Terms, if your use creates risk or possible legal exposure for us or others, if you do not pay, if we are required to by law, or if we stop offering the Services or part of them. We may also block devices, browsers, or IP addresses. If we suspend or terminate your account, you may not create a new account without our written permission. No refund is due when we suspend or terminate, except where the law requires one (see Section 12). Refunds for App Store and Google Play purchases are handled by Apple and Google.

When your account or access ends for any reason, your license to use the Services ends, you lose access to your account and history, and any unused words, credits, and top-up balances are forfeited. The following survive: Section 6 (except the license we grant you), Sections 7 through 10, any payment obligations under Sections 11, 12, and 18, the parts of Section 18 about your end users and data handling, and Sections 19 through 29.

22. Disclaimers

THE SERVICES, INCLUDING ALL OUTPUTS AND DETECTION RESULTS, ARE PROVIDED “AS IS” AND “AS AVAILABLE,” WITHOUT WARRANTIES OF ANY KIND. TO THE FULLEST EXTENT THE LAW ALLOWS, WE DISCLAIM ALL WARRANTIES, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING ANY WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, ACCURACY, AND QUIET ENJOYMENT, AND ANY WARRANTIES ARISING FROM A COURSE OF DEALING OR USAGE OF TRADE.

WITHOUT LIMITING THE ABOVE, WE DO NOT WARRANT THAT: THE SERVICES WILL BE UNINTERRUPTED, SECURE, OR ERROR-FREE; ANY OUTPUT WILL BE ACCURATE, COMPLETE, ORIGINAL, OR SUITABLE FOR YOUR PURPOSE; ANY TEXT WILL RECEIVE ANY PARTICULAR SCORE, LABEL, OR RESULT FROM ANY AI DETECTION TOOL, INCLUDING OURS; ANY DETECTION RESULT WILL BE CORRECT; OR ANY CONTENT WILL BE STORED OR PRESERVED. NOTHING IN THE SERVICES IS LEGAL, MEDICAL, FINANCIAL, OR OTHER PROFESSIONAL ADVICE. YOU USE THE SERVICES AT YOUR OWN RISK, AND YOU ARE SOLELY RESPONSIBLE FOR THE DECISIONS YOU MAKE BASED ON OUTPUTS OR DETECTION RESULTS AND FOR ANY LOSS OF DATA OR DAMAGE TO YOUR DEVICES.

If the law that applies to you does not allow any of these exclusions, they apply to you only to the extent that law allows, and any warranty that cannot be excluded is limited to the shortest period the law allows. If you are a New Jersey resident, the exclusions in this Section 22 and the limits in Section 23 do not apply to any liability that New Jersey law does not allow to be excluded or limited, and the rest of those sections still apply to you.

23. Limitation of Liability

TO THE FULLEST EXTENT THE LAW ALLOWS, WRITE HUMAN LLC, ITS AFFILIATES, AND ITS AND THEIR MEMBERS, MANAGERS, OFFICERS, EMPLOYEES, AGENTS, SUPPLIERS, AND LICENSORS (THE “WRITEHUMAN PARTIES”) WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, BUSINESS, GOODWILL, OR DATA, OR FOR ANY EMPLOYMENT, DISCIPLINARY, OR REPUTATIONAL HARM, ARISING OUT OF OR RELATING TO THESE TERMS OR THE SERVICES, WHETHER THE CLAIM IS BASED ON CONTRACT, TORT (INCLUDING NEGLIGENCE), STATUTE, OR ANY OTHER LEGAL THEORY, AND EVEN IF WE HAVE BEEN TOLD SUCH DAMAGES ARE POSSIBLE.

TO THE FULLEST EXTENT THE LAW ALLOWS, THE TOTAL LIABILITY OF THE WRITEHUMAN PARTIES FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THESE TERMS OR THE SERVICES WILL NOT EXCEED THE GREATER OF (A) THE AMOUNTS YOU PAID FOR THE SERVICES (INCLUDING THROUGH APPLE OR GOOGLE) IN THE 12 MONTHS BEFORE THE EVENT THAT GAVE RISE TO THE LIABILITY, OR (B) US$100. THESE LIMITS APPLY EVEN IF A REMEDY FAILS OF ITS ESSENTIAL PURPOSE, AND THEY ARE AN ESSENTIAL PART OF THE BARGAIN BETWEEN YOU AND US.

Nothing in these Terms excludes or limits any liability that cannot be excluded or limited under applicable law, such as liability for fraud, for death or personal injury caused by negligence, or for gross negligence or willful misconduct where the law does not allow such liability to be limited.

24. Indemnification

To the extent the law allows, you will defend, indemnify, and hold harmless the WriteHuman Parties from and against all claims, demands, and proceedings brought by third parties, and all related losses, damages, liabilities, fines, costs, and expenses (including reasonable attorneys' fees), arising out of or relating to: (a) Your Content; (b) your use of the Services or of Outputs, including how you publish, submit, or represent Outputs; (c) your breach of these Terms or violation of any law or anyone's rights; (d) if you use the Developer Services, your products, your end users, and their content and use of the Services; and (e) any use of your account, keys, or tokens. This obligation does not apply to the extent a claim results from our fraud, gross negligence, or willful misconduct. We may take over the defense and control of any matter you must indemnify us for, at your expense, and you will cooperate with us. You may not settle any such matter without our written consent.

25. Governing Law and Venue

These Terms, and any Dispute between you and us, are governed by the laws of the Commonwealth of Virginia, United States, without regard to its conflict of laws rules. The Federal Arbitration Act governs the interpretation and enforcement of Section 26. The United Nations Convention on Contracts for the International Sale of Goods and the Uniform Computer Information Transactions Act, as enacted in any jurisdiction, do not apply.

Subject to Section 26, any lawsuit between you and us that is allowed to proceed in court must be brought only in the state courts located in Chesterfield County, Virginia, or in the United States District Court for the Eastern District of Virginia, Richmond Division, and you and we consent to the personal jurisdiction and venue of those courts. Either party may bring a claim in small claims court as described in Section 26.

26. Dispute Resolution and Binding Arbitration

This section requires you and us to resolve disputes through individual arbitration, and it limits how you can seek relief from us.

(a) What this section covers.

“Dispute” means any dispute, claim, or controversy between you and us (including our affiliates, and our and their members, managers, officers, employees, and agents) that arises out of or relates in any way to these Terms, the Services, any purchase, any communication or advertising from us, or your relationship with us, whether based on contract, tort, statute (including privacy, data protection, consumer protection, and wiretapping laws), fraud, misrepresentation, or any other legal theory. This includes Disputes that arose before you accepted these Terms, but not Disputes that were the subject of a lawsuit or arbitration already filed before you accepted this version of these Terms.

(b) Informal resolution comes first.

Before starting an arbitration or small claims case, the party with a Dispute must send the other a written Notice of Dispute. Notices to us must be sent by email to support@writehuman.ai with the subject line “Notice of Dispute,” or by mail to Write Human LLC, 1224 Shirlton Rd, Midlothian, VA 23114, United States. We will send notices to the email address on your account. A Notice of Dispute must be individual to one person and must include: that person's name, the email address on their account (if any), and how to contact them; a description of the Dispute and the facts it is based on; and the specific relief requested. A Notice from you must be personally signed by you (and by your lawyer, if you have one).

For 60 days after the Notice is received, you and we will try in good faith to resolve the Dispute informally. During that period, either party may ask for an individual settlement conference by phone or video, which you (and a representative of ours) must personally attend; your lawyer may also attend. Completing this process is a condition to starting an arbitration or small claims case, and a court may enforce it, including by stopping a case that was started without completing it. Any statute of limitations and filing fee deadline is paused (tolled) from the date the Notice is received until the end of this 60-day period.

(c) Binding individual arbitration.

If a Dispute is not resolved informally, it will be resolved only by final and binding arbitration before a single arbitrator, except as provided in subsection (f). The arbitration will be administered by the American Arbitration Association (“AAA”). If you are an individual using the Services for personal purposes, the AAA Consumer Arbitration Rules apply. Otherwise, including for Disputes about your use of the Developer Services on behalf of a business, the AAA Commercial Arbitration Rules apply. In either case, any AAA supplementary rules for mass arbitrations also apply to the extent consistent with subsection (g). The AAA rules are available at adr.org. If the AAA is unavailable or refuses to administer the arbitration, the parties will agree on another arbitration provider, or a court will appoint one.

For consumer arbitrations, hearings will take place by video or phone, or on written submissions, unless the arbitrator decides an in-person hearing is needed, in which case it will take place in the county where you live or another place we both agree to. For other arbitrations, any in-person hearing will take place in Richmond, Virginia. Payment of all filing, administration, and arbitrator fees is governed by the AAA rules. The arbitrator may award any individual relief that a court could award under applicable law, but only in favor of the individual party seeking relief and only to the extent needed to provide relief on that party's individual claim. Each party bears its own attorneys' fees and costs unless the arbitrator awards them under applicable law. The arbitrator's award is final and binding, and judgment on it may be entered in any court with jurisdiction.

(d) Who decides what.

The arbitrator has exclusive authority to decide all issues about the interpretation, applicability, scope, enforceability, and formation of this arbitration agreement, including any claim that all or part of it is void or voidable. However, a court, not an arbitrator, has exclusive authority to decide: (1) disputes about the class action and representative waivers in subsection (e), including whether they are enforceable; (2) disputes about subsection (g) (Mass filings); and (3) whether a party has satisfied subsection (b) (Informal resolution comes first).

(e) Class action and jury trial waivers.

YOU AND WE EACH AGREE THAT DISPUTES WILL BE RESOLVED ONLY ON AN INDIVIDUAL BASIS, AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY CLASS, COLLECTIVE, CONSOLIDATED, PRIVATE ATTORNEY GENERAL, OR REPRESENTATIVE PROCEEDING, IN ARBITRATION OR IN COURT. THE ARBITRATOR MAY NOT CONSOLIDATE MORE THAN ONE PERSON'S CLAIMS (EXCEPT AS SUBSECTION (g) PROVIDES FOR ADMINISTRATION) OR PRESIDE OVER ANY FORM OF CLASS OR REPRESENTATIVE PROCEEDING. YOU AND WE EACH WAIVE ANY RIGHT TO A JURY TRIAL, TO THE EXTENT THE LAW ALLOWS.

If a court decides, after all appeals, that the class, collective, and representative action waiver in this subsection cannot be enforced as to a particular claim or request for relief (such as a request for public injunctive relief), then that claim or request (and only that one) will be severed from the arbitration and decided by a court under Section 25, after the arbitration of all other claims is finished. It will never proceed as a class arbitration. Whether the jury trial waiver can be enforced has no effect on whether a claim is arbitrated. That waiver applies only to claims that proceed in court, to the extent the law allows.

(f) Small claims and intellectual property injunctions.

Instead of arbitration, either party may bring an individual claim in small claims court in the county where you live or in Chesterfield County, Virginia, if the claim qualifies and stays in that court on an individual basis. Either party may also bring a lawsuit in court seeking only an injunction or other equitable relief to stop the actual or threatened infringement, misappropriation, or misuse of its copyrights, trademarks, patents, or trade secrets. This exception does not cover any claim for damages, or any Dispute about Your Content, Outputs, or the license in Section 8, which must be resolved under this section. These are the only exceptions to arbitration.

(g) Mass filings.

If 25 or more Notices of Dispute or demands for arbitration raising similar claims are submitted against us, or by us, by or with the help of the same or coordinated lawyers or organizations (a “Mass Filing”), the following applies in addition to the rest of this section:

  • Each claimant must still complete subsection (b) individually.
  • If either side asks, counsel for the claimants and we will first take part in a single global mediation of all the claims in the Mass Filing, and we will pay the mediator's fees. The claims will be on hold, and no arbitration fees will be due for them, during the mediation, for up to 60 days.
  • After that, the claims will be filed with the AAA in batches of up to 100 claims each. To the extent the AAA's rules allow, each batch will be assigned to a single arbitrator where practical and treated as one case for administrative fee purposes, but each claimant's claim will be decided individually. The AAA will administer the batches as promptly as its resources allow, and a batch may begin before an earlier batch is finished.
  • Any statute of limitations for a claim in a Mass Filing is paused (tolled) from the date its Notice of Dispute is received until its batch is filed.

A court may enforce this subsection, including by ordering that filings or fees be handled consistently with it.

(h) Other terms of this section.

Nothing in this section prevents you from bringing an issue to the attention of a government agency. Except as stated in subsection (e), if any part of this section is found to be unenforceable, the rest of it remains in effect. Changes to this section are subject to the limits in Section 2. This section survives the end of these Terms and of your use of the Services.

28. General Terms

  • Entire agreement. These Terms, including any plan details, offer terms, or other terms they include under Section 1, are the entire agreement between you and us about the Services and replace any earlier agreements or understandings about them. A separate written agreement signed by you and us controls to the extent it conflicts with these Terms.
  • Electronic communications and notices. You agree to receive agreements, notices, disclosures, and other communications from us electronically, by email to the address on your account or through the Services, and you agree that they satisfy any legal requirement that they be in writing. You also agree to the use of electronic signatures and records. We may send you emails about your account, purchases, security, and changes to the Services. You are responsible for keeping your email address current. Notices to us must be sent to the contact details in Section 29, except as Section 26 provides.
  • Assignment. We may assign or transfer these Terms, in whole or in part, without notice or your consent, including in connection with a merger, acquisition, or sale of assets. You may not assign or transfer these Terms or your account without our written consent, and any attempt to do so is void.
  • Severability. Except as stated in Section 26, if any provision of these Terms is found to be unenforceable, it will be enforced to the maximum extent permissible or severed, and the rest of these Terms will remain in effect.
  • Time limit for claims. To the extent the law allows, you and we must each bring any claim arising out of or relating to these Terms or the Services within one year after the claim arose, plus any time the claim was paused under Section 26. Otherwise, the claim is permanently barred. This limit does not apply to any claim for which the law does not allow the limitation period to be shortened by agreement.
  • No waiver. Our failure to enforce any right or provision of these Terms is not a waiver of that right or provision.
  • Force majeure. We are not liable for any delay or failure to perform caused by events beyond our reasonable control, including natural disasters, pandemics, war, terrorism, riots, labor disputes, government actions, internet or utility failures, failures of our service providers, and cyberattacks.
  • Export controls and sanctions. You may not use or export the Services in violation of U.S. or other applicable export control or sanctions laws. You confirm that you are not located in, or ordinarily resident in, a country or region subject to comprehensive U.S. sanctions, and that you are not on any U.S. Government list of prohibited or restricted parties.
  • Survival. Any provision of these Terms that by its nature should survive the end of these Terms will survive, including the provisions listed in Section 21.
  • Relationship and third parties. These Terms do not create any partnership, joint venture, employment, or agency relationship between you and us. Except for Apple as described in Section 16 and the WriteHuman Parties under Sections 22 through 24, there are no third-party beneficiaries of these Terms.
  • Interpretation. Headings are for convenience only. “Including” means “including without limitation.” These Terms will not be interpreted against us because we wrote them. If we provide a translation of these Terms, the English version controls.
  • Notice to California users. Under California Civil Code Section 1789.3, California users are entitled to the following notice: the Complaint Assistance Unit of the Division of Consumer Services of the California Department of Consumer Affairs may be contacted in writing at 1625 North Market Blvd., Suite N 112, Sacramento, CA 95834, or by telephone at (800) 952-5210. Our name, address, and telephone number are listed in Section 29.
