Casetext was an AI-powered legal research company founded in 2013 and backed by Y Combinator. Its platform offered case law search and AI tools for legal research, document review, contract analysis and deposition preparation, and in 2023 it launched CoCounsel, a GPT-4-based AI legal assistant. Thomson Reuters acquired Casetext for $650 million in August 2023, retired the standalone Casetext service on April 1, 2025, and continues CoCounsel within its Westlaw and CoCounsel product line.
