Terms of Use

Last updated: 18 October 2026

By using Turnitin AI Detector you agree to these terms. If you do not agree, please do not use the site.

What the service does

Turnitin AI Detector is a free tool that estimates how likely it is that an English text was written with the help of AI. It shows how much of the text reads as AI-like (as a percentage of its words), a label, a separate estimate for the whole text and a score for each sentence. The results are automated estimates and can be wrong. Please read our Disclaimer before relying on a result.

Using the service fairly

You agree not to:

  • submit text that you do not have the right to share, or that breaks any law;
  • submit personal, confidential or sensitive information about yourself or other people;
  • use bots or scripts to send checks, get around the usage limits, or overload the site;
  • copy, resell or build another service on top of the results or the site without our written permission;
  • use a result alone to accuse, grade, punish or make a decision about a person.

Usage limits

To keep the service free, the number of checks per visitor and the total number of checks per day are limited. When a limit is reached you will see a message saying when you can try again. We may change these limits at any time.

Your text

You keep all rights to the text you submit. You allow us to send it to our detection provider only to produce your result. How your text is handled is explained in our Privacy Policy.

No warranty

The service is provided "as is" and "as available", without any warranty. We do not promise that results are accurate or complete, or that the site will always be available or free of errors.

Limitation of liability

To the fullest extent allowed by law, we are not liable for any loss or damage that comes from using the site or relying on its results, including academic, employment or business decisions made by you or by others.

Changes and ending the service

We may change, pause or stop the service, or update these terms, at any time. The date at the top shows the latest version. If you keep using the site after a change, you accept the updated terms.
