Disclaimer

IsThisAiWritten gives a quick, private first check of whether a text may have been written by AI. Please read what that can and can't tell you before relying on it.

Results are estimates, not proof

Detection results are statistical estimates. They can be wrong in both directions: human writing can be flagged as AI, and AI writing can pass as human. Our measured error rates, including what the detector misses, are published on the methodology page. Never use a result as the only evidence for a grade, a disciplinary step, an employment decision or a public accusation.

No professional advice

Articles on this site explain how AI detection works and compare tools. They are general information, not legal, academic-integrity or professional advice. If a decision affects your studies, job or legal position, ask the institution or a qualified adviser.

Information about other products

Facts about other detectors come from their public pages and are dated on each page. Prices, limits and features change often, so check the company's own site before you rely on them. Product names belong to their owners, and we are not affiliated with or endorsed by any company we compare. How we write comparisons is set out in our editorial policy.

Advertising

Some articles and guides show ads served by Google AdSense. Ads are chosen by Google, not by us, and are not endorsements. No company pays to be mentioned or ranked in our content. Ads never appear on pages where you paste text. How ads use cookies is explained in our privacy policy and on our cookie page.

Links to other websites

We link to sources and to other companies' sites so you can check our facts. We don't control those sites and aren't responsible for their content or their privacy practices.

No warranty

The service and the content are provided as they are, without any warranty, to the extent the law allows. Our terms of use apply. Questions or corrections: [email protected].
