What is Casetext (CoCounsel)?

Casetext CoCounsel is an AI-powered legal research assistant that became one of the first legal tech platforms to integrate GPT-4 into professional legal workflows. Acquired by Thomson Reuters in 2023, CoCounsel provides attorneys with a suite of AI skills specifically designed for legal work. The platform can review documents for relevant information, conduct legal research across vast databases of case law, prepare deposition outlines, and extract key contract provisions in minutes rather than hours. What distinguishes CoCounsel from generic AI tools is its rigorous approach to legal accuracy: every citation is verified against actual case databases, dramatically reducing the hallucination risks that plague general-purpose AI in legal contexts. The document review skill can process hundreds of documents simultaneously, identifying relevant passages and organizing findings by legal issue. Attorneys can use natural language queries like asking which contracts contain change of control provisions or what the opposing party's arguments were in similar cases. CoCounsel's timeline creation feature automatically maps out case chronologies from document sets, saving paralegals days of manual work. The platform integrates with Westlaw through its Thomson Reuters ownership, giving users access to the most comprehensive legal database alongside AI analysis capabilities. Pricing is per-seat with annual contracts, positioning it as an investment for firms handling significant research and review workloads.
