Thomson Reuters CoCounsel
AU MarketProfessional AI legal assistant built on 174 years of Thomson Reuters trusted content
Overview
CoCounsel is Thomson Reuters' professional-grade AI legal assistant, built on 174 years of trusted legal content and powered by 1,000+ AI and data science professionals. It delivers AI-assisted legal research grounded in Westlaw and Practical Law, advanced document analysis (review, compare, summarise, timeline creation), drafting automation with built-in proofing, and knowledge search across your own work product. CoCounsel holds ISO/IEC 42001:2023 certification for AI management systems — the first major legal AI platform to achieve this standard. For Australian firms, all customer prompts, content, and outputs are hosted and processed locally in Australia, addressing data sovereignty and compliance requirements. A dedicated local team of AI and legal specialists supports Australian customers.
Key Capabilities & Differentiators
CoCounsel grounds all research outputs in Thomson Reuters' authoritative content databases (Westlaw, Practical Law), rather than the open internet, significantly reducing hallucination risk. A dedicated Trust Team of lawyers runs over 1,500 automated tests nightly to validate output quality. The platform' ISO/IEC 42001:2023 certification provides independent assurance of AI governance practices. For Australian customers, all data is hosted and processed locally, and a local team of AI and legal specialists provides support. CoCounsel does not use customer content or prompts to train its models.
