What it does

Casetext is an AI-native legal research and drafting platform - now part of Thomson Reuters - best known for CoCounsel, one of the first GPT-4-powered AI legal assistants. CoCounsel performs substantive legal tasks: researching case law and statutes, reviewing and summarizing contracts and documents, drafting legal memos and briefs, and analyzing deposition transcripts for key facts. Unlike traditional legal research tools that return lists of cases for lawyers to read, CoCounsel synthesizes legal research and provides analysis - dramatically reducing the time attorneys spend on research and document review. Casetext's integration with Thomson Reuters gives it access to Westlaw's legal database, combining AI reasoning with the most comprehensive legal content library.

Strengths

Mid-market law firms and in-house legal departments use Casetext for systematic AI-assisted legal work - document review, research, and drafting across the team with consistent quality.
Large law firms and corporate legal departments use Casetext at enterprise scale - AI handling high-volume document review, accelerating research, and drafting first passes on complex matters.
Small businesses with in-house legal needs use Casetext for contract review and legal research - AI reducing external counsel dependence for routine legal analysis.
Small law firms use CoCounsel to compete with larger firms on research quality - AI synthesizing case law and drafting memos at the speed of a large firm's associate team.
Solo practitioners use Casetext CoCounsel to access capabilities previously requiring associates - AI legal research and document review enabling one attorney to handle workloads that would otherwise require a team.

Watch-outs

AI legal analysis requires attorney review: CoCounsel's research and drafting outputs must be reviewed by a licensed attorney before use — AI can hallucinate citations or mischaracterize legal holdings, and professional responsibility requires attorney supervision of AI-generated work product.
Thomson Reuters integration changes product trajectory: Casetext's acquisition by Thomson Reuters means its independent roadmap has merged with Westlaw's — some users report uncertainty about standalone product development versus integration into the broader Thomson Reuters ecosystem.
Primarily US legal system focused: Casetext's legal database and AI models are trained on US law — attorneys working in non-US jurisdictions find coverage and accuracy significantly reduced outside the US legal system.
