Our AI component is not restricted to a specific legal system or jurisdiction. However, the legal database search is limited to the United States.

Cetient is free for personal and professional use, with a limit of 42 messages per month. Pro plan is $79/month or $66/month when billed annually.
How accurate is this?
We use generative AI models. The output may contain hallucinations and inaccurate information. You are responsible for reviewing and verifying the accuracy, appropriateness, and completeness of the content. We will do our best to include links to the full text of court opinions to assist you with the verification.
Do you provide legal advice?
