Our mission
Our mission is to give legal professionals and the general public the superpower to understand the law.
How does Cetient work?
Cetient uses AI to search, analyze, and summarize US case law and draft documents. Think of ChatGPT that has direct access to legal databases like LexisNexis or Westlaw.1
What is Cetient?
Cetient has access to over 9 million legal decisions from 2000+ U.S. federal and state courts. With Cetient AI, lawyers, paralegals, clerks, pro se litigants, law students, and the public can easily research important cases, understand legal concepts and procedures, draft documents, and conduct in-depth analysis using our legal data.
Which legal system does it apply to and can be used in?
Our AI component is not restricted to a specific legal system or jurisdiction. However, the legal database search is limited to the United States.
How much does it cost?
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?
We are not attorneys or a law firm. Our platform is not intended to provide legal advice. Users should not ask legal questions or seek legal advice through our services.
