Terms of use

By using HumanizerAI you agree to these terms. The plain-language summary: use the tools freely, treat every output as a draft, and don't treat any score or rewrite as a promise about detectors, grades or publication outcomes.

What the tools are

Rewrite aids. The humanizer, rewriter and paraphrasing tool transform the text you supply according to the selected mode; they keep your facts, numbers and names to the best of the engine's ability but can make errors of emphasis or nuance. Every output must be proofread by you before use. The detector is a heuristic reference score of statistical style — it is not a forensic authorship test and must never be used to accuse anyone, in a classroom, a workplace, or anywhere else.

Acceptable use

Don't use the tools to produce deceptive, harassing, or infringing content; don't attempt to bypass the free-tier limits or resell access; don't paste content you have no right to process (you keep the rights and responsibility for everything you paste). We enforce free-tier limits server-side and may throttle abusive traffic without notice — which is why the 503 “capacity” state exists.

Payments

Credit packs ($2.99 / 30,000 words) are one-time purchases processed by PayPal. Words attach to an anonymous browser token; clearing browser storage discards unused words, which we cannot restore. If a payment posts but words do not appear, contact us with the payment date and amount and we will fix it or refund.

Trademarks

QuillBot, Learneo, ZeroGPT, GPTZero and all related marks are trademarks of their respective owners. This independent site is not affiliated with, endorsed by, or sponsored by any of them. Product names appear nominatively, to describe the tools people compare against.

No warranty

The tools are provided "as is" without warranty of any kind. We make no promise that output will suit any particular purpose, pass any detector, satisfy any institution's AI policy, or remain error-free, and we are not liable for decisions made on the basis of tool output — including submitted assignments or published copy.

Changes

These terms may be updated; continued use after a change constitutes acceptance. Tools and pages may also change or be retired — this is a free utility site, not a service contract.
