Thomson Reuters has announced that one million professionals in high-stakes industries - legal, risk, compliance, tax, accounting, audit, and global trade - now rely on CoCounsel, the company's professional-grade AI technology. Spanning 107 countries and territories, this milestone signals a decisive shift from AI experimentation to production-grade adoption embedded in daily workflows where accuracy, authoritative sourcing, and data protection are non-negotiable.

"Professionals are not deciding whether to use AI anymore. They are deciding which AI they trust when their reputation and their clients' data are on the line," said Steve Hasker, President and Chief Executive Officer, Thomson Reuters. "CoCounsel is built for moments when being almost right is not good enough. It is grounded in decades of authoritative content, validated by domain experts, and backed by a clear commitment that customer data remains theirs. That is why one million professionals rely on CoCounsel."
"When the work matters, the AI must be professional grade. Professionals need systems that can complete sophisticated work within the standards they are accountable to every day. That's the gap between CoCounsel and everything else," added David Wong, Chief Product Officer, Thomson Reuters. "One million CoCounsel users across 100+ countries and territories reflects a shared global consensus."
General-purpose AI excels at generating plausible responses but falls short in regulated environments requiring verifiable authority, jurisdictional accuracy, and defensible outputs. CoCounsel bridges this gap by functioning as a vertically integrated execution layer: it retrieves from trusted sources (Westlaw, Practical Law), applies expert-validated logic, analyzes user documents and precedent, confirms citations remain valid, and produces structured, auditable results—all within familiar professional systems.
The platform's design decisions—licensed content, expert oversight, workflow integration, strict data boundaries, and multi-model governance—enable it to support high-consequence work without compromising trust or compliance.
With one million users, CoCounsel demonstrates that AI's value in professional services lies not in speed of text generation but in its ability to reliably execute tasks carrying legal or financial consequences.
