Thomson Reuters taps CUBE for legal AI regulatory data

CUBE will provide regulatory intelligence for Thomson Reuters CoCounsel Legal, extending the platform's regulatory coverage to users in more than 150 countries.

Under the arrangement, CoCounsel Legal users will be able to access laws, rules, regulations and recent regulatory developments through a connection between Thomson Reuters' AI agents and CUBE's regulatory AI agents. The setup means Thomson Reuters does not need to ingest, structure or maintain the underlying regulatory data itself.

CoCounsel Legal is used by corporate legal teams and international law firms. It already includes access to Thomson Reuters Westlaw, Practical Law and Reuters content. CUBE's material has now been added to broaden the regulatory picture for legal professionals working across jurisdictions.

Benchmark testing

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

For regulatory guidance, codes and supervisory material, CUBE said the gap was wider, ranging from six to 17 times more than the other models, depending on the model tested. Thomson Reuters subject matter experts also evaluated the regulatory intelligence and concluded that, alongside Westlaw and Practical Law, the additional content gave users a fuller view of rules, guidance and regulatory developments.

The claim goes 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 present the integration as an example of 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. 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," said Ben Richmond, Founder and Chief Executive Officer, CUBE.

Data depth

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

The scale of that underlying corpus is a key selling point in areas where 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. That is especially relevant for cross-border work, where obligations can differ sharply between markets and legal and compliance teams often have to track changes across multiple regulators.

Thomson Reuters said global coverage and quality were key requirements in choosing a regulatory intelligence provider for CoCounsel Legal. It added that the service is available to 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. 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," said Rawia Ashraf, Co-Head of Product, Thomson Reuters Legal.

Market focus

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 is distributing that data via other platforms and information providers rather than only through its own products.

The deal also reflects a broader pattern in professional services software, where providers are combining proprietary content, specialist datasets and AI tools to improve the quality of answers 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.

CUBE said its regulatory intelligence spans more than 12,000 issuing bodies across 750 jurisdictions and is supported by 250 regulatory and legal experts.
