Thomson Reuters Taps CUBE to Feed Regulatory Data Into CoCounsel Legal AI

Thomson Reuters has signed CUBE to supply regulatory intelligence for CoCounsel Legal, extending the platform's regulatory coverage to users in more than 150 countries, the two companies announced on November 13, 2026.

The arrangement lets CoCounsel Legal users access laws, rules, regulations and recent regulatory developments through a connection between Thomson Reuters' AI agents and CUBE's regulatory AI agents. That architecture matters for Thomson Reuters: it does not need to ingest, structure or maintain the underlying regulatory data itself.

CoCounsel Legal serves corporate legal teams and international law firms. It already bundles access to Thomson Reuters Westlaw, Practical Law and Reuters content. CUBE's material now broadens the regulatory picture for legal professionals working across jurisdictions.

What did the benchmark testing show?

CUBE said benchmark testing compared its regulatory identification agent with two frontier AI models across 13 queries covering the UK, Spain and the UAE. The company's system found three to four times more essential regulation than the rival models, according to CUBE.

For regulatory guidance, codes and supervisory material, CUBE said the gap widened considerably. Its system returned six to 17 times more than the other models, depending on the model tested.

Thomson Reuters subject matter experts also evaluated the regulatory intelligence. They concluded that, alongside Westlaw and Practical Law, the added content gave users a fuller view of rules, guidance and regulatory developments.

The claim speaks to a central question in legal AI: whether large language models alone can produce reliable answers in specialist regulatory work without access to structured, verified source material. The companies frame the integration as one AI system drawing on another provider's domain-specific data, rather than relying solely on general-purpose models and web search.

"Our ambition is simple: to be the regulatory data infrastructure the world can trust, and to power the products, AI tools and workflows that enterprises rely on to deliver smarter and better-informed outcomes," said Ben Richmond, Founder and Chief Executive Officer of CUBE. "We believe that delivering regulatory intelligence, at the point of need, is the future of our industry. With CoCounsel Legal, our Powered By AI agents bring expert-checked regulatory intelligence into the tools that legal professionals already use, helping them build a more complete picture of the rules and guidance relevant to their questions."

How deep does CUBE's data go?

CUBE said its regulatory intelligence has been built over 15 years. It covers more than 12,000 issuing bodies across 750 jurisdictions, enriched by 250 subject matter experts and checked by humans throughout the process.

That depth is the key selling point. Legal teams must understand not only statutes and case law, but also guidance, supervisory notices and other materials that shape how regulation is applied in practice. The stakes are highest in cross-border work, where obligations can differ sharply between markets and legal and compliance teams often track changes across multiple regulators at once.

Thomson Reuters said global coverage and quality were key requirements in choosing a regulatory intelligence provider for CoCounsel Legal. The company added that the service reaches up to 1 million legal professionals.

"Legal professionals working across borders need to understand not just the law, but the full regulatory landscape that shapes how that law applies in practice," said Rawia Ashraf, Co-Head of Product, Thomson Reuters Legal. "Bringing CUBE's expert-checked regulatory intelligence into CoCounsel Legal extends our already extensive global content reach, giving our customers an even richer and more complete picture of the rules, guidance and regulatory developments relevant to their work. Global coverage and quality were both non-negotiable for us, and CUBE met both."

Why is CUBE selling its data through other platforms?

CUBE already supplies regulatory intelligence to heavily regulated institutions, including 24 of the world's 29 Global Systemically Important Banks, according to the company. Through its Powered By offering, it distributes that data via other platforms and information providers rather than only through its own products. The Thomson Reuters deal is the pattern in action.

The arrangement also reflects a broader shift in professional services software. Providers are combining proprietary content, specialist datasets and AI tools to improve answer quality in high-risk work. For legal and compliance teams, the commercial value often rests less on the chatbot interface than on the provenance, coverage and verification of the underlying material.

That logic explains the deal from both sides. Thomson Reuters buys verified depth it would be costly to build. CUBE buys distribution at scale through one of the largest legal software platforms on the market.

CUBE reiterated the scale of its corpus in announcing the deal: regulatory intelligence spanning more than 12,000 issuing bodies across 750 jurisdictions, supported by 250 regulatory and legal experts. Expect more integrations of this shape, as vendors competing on AI answers increasingly compete on whose data the agents can actually reach.
