Casetext

Casetext is a legal research platform that uses artificial intelligence to help lawyers and legal professionals find the case law, statutes, and regulations they need. Instead of manually sifting through dense legal databases with complex keyword searches, you can ask a question in plain English or upload a legal document. The tool's AI, named CoCounsel, analyzes your query to pull up the most pertinent legal authorities, saving hours of manual research time.

What makes Casetext stand out is its focus on context and reasoning. Its core AI, CoCounsel, doesn't just find cases with matching keywords; it reads and comprehends the legal principles within them. Key features include the ability to search by legal concept, get AI-generated summaries of cases, and check citations for validity. You can also upload a brief or memo and ask the AI to find supporting or opposing authorities, making it a powerful assistant for building arguments.

This tool is a major time-saver for practicing attorneys, law firm associates, and legal academics. It's particularly useful for drafting motions and briefs, preparing for trial or hearings, and getting up to speed on a new area of law quickly. For solo practitioners or small firms without large research budgets, it provides a level of research power that was previously only accessible to big law libraries.
