Terms of service

Last updated 14 November 2026

These terms apply when you use Kerata, the website and API at this address. In these terms “Kerata”, “we” and “us” mean the team that runs this service. By using Kerata or creating an account you agree to them. Questions: the contact page.

1. The service

Kerata estimates whether source code resembles code written by AI models, highlights the parts that look most AI-like, compares submissions for similarity and helps instructors review the results.

2. Public beta

Kerata is in public beta and free to use within the limits published on the pricing page. Features and limits may change during the beta; we'll post changes to limits on that page before they take effect. There are no paid plans yet; if we introduce them, their terms will be shown before you buy anything.

3. Results are estimates, not proof

Kerata's results are probabilistic. They are not proof of authorship, AI use or misconduct, and must not be the only basis for an academic, disciplinary or employment decision. If you use a result to make a decision about someone, you agree to have a person review the evidence and to give the person concerned a fair chance to respond.

4. Your account

Keep your sign-in details and API keys secret; you're responsible for what happens under your account. Workspace owners decide who joins their workspace and what is uploaded to it.

5. Your content

You keep all rights in the code and other material you submit. You give us permission to process it only to run the service for you: to analyze it, to store it in your history and workspace if you're signed in, and to show it through share links you create. You confirm you have the right to submit it, for example under your institution's rules for student work. We don't sell your content or use it to train models.

6. Acceptable use

Don't use Kerata for anything unlawful; don't try to break, overload, probe or reverse-engineer it; don't get around its limits (for example with many accounts or automated anonymous requests); don't resell access without our agreement; and don't use results to harass or shame anyone.

7. Availability and warranty

Kerata is provided “as is” and “as available”. During the beta there is no service-level commitment: the service may be slow, interrupted or changed, and results may be wrong.

8. Liability

To the extent the law allows, we aren't liable for indirect or consequential losses, or for decisions anyone makes based on a result, and our total liability to you is limited to the amount you paid us for the service in the 12 months before the claim. Nothing in these terms limits liability that can't be limited by law.

9. Ending

You can stop using Kerata and delete your account at any time (Settings → Delete account). We may suspend or close accounts that break these terms or put the service or other users at risk.

10. Changes to these terms

We'll post updated terms here with a new date. If a change is significant, we'll email account holders before it takes effect. Continuing to use Kerata after a change means you accept the updated terms.
