What is Cetient?
Cetient is an AI-powered legal research tool with access to over 9 million legal decisions from 2000+ federal and state courts. With Cetient AI, lawyers, paralegals, clerks, law students, and the public can easily research important cases, stay updated with evolving case law, or conduct in-depth analysis using our legal data.
How does Cetient help with the legal research?
Cetient can search, analyze, and summarize US case law. Think of ChatGPT that has direct access to legal databases like LexisNexis or Westlaw.1
To which legal system is it applied and usable?
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 completely free for personal and professional use.
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.
