Thomson Reuters is enhancing its CoCounsel Legal AI platform with new features: workspaces, a Brief Builder AI agent, and organizational intelligence. These updates, announced by Thomson Reuters, respond to feedback from beta users aiming to streamline in-house and law firm workflows ahead of the platform's general release in August 2026 (Thomson Reuters announcement).
The next-gen CoCounsel acts as a unified agentic platform, capable of planning, selecting tools, and retrieving authoritative content dynamically. Ragunath Ramanathan, President of Legal Professionals at Thomson Reuters, described it as functioning "like a senior associate would, not a first-year waiting for the next instruction" (R. Ramanathan quote), highlighting its adaptability for complex multistep legal tasks via a single conversational interface.
Integration with existing systems like Westlaw, Practical Law, Microsoft 365, and popular document management platforms ensures CoCounsel provides a cohesive experience. This assists legal departments and law firms managing document automation and review processes across varied toolsets.
CoCounsel's adoption exceeds one million users across 107 countries and territories, reflecting its broad acceptance (Adoption metrics). Users report a 2.6-times increase in speed for document review and contract drafting. Steven Hicks-Safra, General Counsel at Cole, Scott & Kissane, shared that tasks formerly requiring eight to nine hours now take under two hours with CoCounsel (Hicks-Safra interview).
These advances demonstrate the transition from legal AI experimentation to deployment focused on boosting operational efficiency and accuracy in legal departments and law firms.
By the numbers:
- 1 million+ users — across 107 countries and territories use CoCounsel
- 2.6x faster — document review and contract drafting with CoCounsel
- August 2026 — planned general release date for next-gen CoCounsel
What's next: Watch for Thomson Reuters' general release of next-gen CoCounsel in August 2026, with further updates expected post-launch.
