CoCounsel Hits One Million Users

Thomson Reuters' AI platform CoCounsel has reached one million users across 107 countries, marking a shift from AI pilots to production systems.

Thomson Reuters announced on February 24, 2026, that one million professionals now use CoCounsel, its professional-grade AI platform, across 107 countries and territories, as regulated industries move from testing AI tools to embedding them into daily workflows.

This milestone matters because it signals that AI adoption in high-stakes fields like law, tax, and compliance has crossed a critical threshold. Professionals are no longer evaluating AI; they are depending on it for work that carries legal and financial consequences.

The Core Problem

General-purpose AI tools can produce plausible-sounding answers, but they fall short in regulated environments. Legal, tax, and compliance professionals need outputs that hold up in courtrooms, audits, and regulatory proceedings.

These professionals require AI that retrieves authoritative sources, verifies citations, and applies jurisdiction-specific rules. A system that gets things mostly right is not acceptable when errors carry professional or legal consequences.
