Thomson Reuters' agentic legal AI grounded in Westlaw and Practical Law — handles legal research, document review, contract analysis, drafting in Word, and depositions prep with verified citations.
CoCounsel is the legal AI built originally by Casetext, acquired by Thomson Reuters in 2023, and now positioned as the flagship product of Thomson Reuters' AI strategy — woven into Westlaw, Practical Law, HighQ, and Legal Tracker. The defining technical claim, repeated across the Thomson Reuters site and customer stories, is grounding: every response is anchored to Westlaw's authoritative legal database (150 years of editorial expertise), Practical Law's templates and guides curated by 650+ attorney-editors, and the customer's own uploaded documents — with citation verification built in. Functionally, CoCounsel handles document review and analysis (privilege, key terms, deviations), contract review with risk assessment, grounded legal research with Westlaw citations, deposition preparation, drafting inside Microsoft Word, agentic multi-step workflow orchestration, and bulk document processing. Customer stories on the public site put the value in measurable terms: Justly Prudent achieving 5x ROI and 100% increase in litigation capacity, Brinks streamlining legal work and cutting outside counsel spend, Harris Hardy & Johnstone reducing hour-long reviews to minutes, and the Pascua Yaqui Tribe transforming matter management with HighQ. Pricing is enterprise-only, sold by seat with annual contracts — typical legal AI economics — and falls squarely into Thomson Reuters' procurement motion.
