CaseText CoCounsel

CoCounsel by CaseText (now part of Thomson Reuters) is an AI legal assistant built on GPT-4 specifically for legal professionals. It performs comprehensive legal research by searching case law, statutes, and regulations, then synthesizing findings into structured memos with proper citations. The AI can review documents for relevant information, analyze contracts to identify key provisions and risks, prepare deposition outlines, and extract information from large document sets. Each output includes citations to source material that lawyers can verify. CoCounsel is designed with legal-specific guardrails: it flags uncertainty, avoids hallucinating citations, and clearly distinguishes between established law and its analysis. It handles tasks that typically take junior associates hours in minutes, allowing lawyers to focus on strategy and client relationships.
