CoCounsel

CoCounsel is Thomson Reuters' flagship AI legal assistant — the only AI tool in the market built directly on Westlaw Precision Australia, Practical Law, and 174 years of curated, authoritative legal content. Unlike general-purpose AI tools that draw from the open internet, CoCounsel's answers are grounded in verified, jurisdiction-specific legal sources, with full citations you can check. It holds ISO/IEC 42001:2023 AI management system certification — the international standard for responsible AI — and is one of the few legal AI platforms to achieve this independently verified benchmark.

For Australian law firms, CoCounsel offers a compelling combination of depth and safety: all customer data is hosted and processed in Australia, your content is never used to train third-party models, and a dedicated Trust Team of lawyers runs over 1,500 automated accuracy tests every night. The result is a platform that accelerates research, drafting, document review, and knowledge search — while giving partners the confidence that outputs are traceable, accurate, and ethically governed. Firms already using Westlaw, Practical Law, HighQ, iManage, or Microsoft 365 will find CoCounsel integrates seamlessly into their existing workflows.
