Casetext was founded in 2013 and pioneered AI-driven legal research. In March 2023 it launched CoCounsel — the first GPT-4 legal AI assistant — and was acquired by Thomson Reuters in June 2023 for $650M. The Casetext brand still exists for the standalone research platform; CoCounsel itself has been folded into Westlaw Precision and the Thomson Reuters AI suite.
