Thomson Reuters has added CUBE’s regulatory intelligence to CoCounsel Legal, giving lawyers a way to research both the rules that apply to a client and the guidance regulators have issued on how to follow them.
When a lawyer asks a regulatory question, CoCounsel’s AI agents can call on CUBE’s agents to retrieve relevant rules, codes and supervisory guidance. That material sits alongside Westlaw, Practical Law and Reuters reporting. CUBE says it tracks more than 12,000 issuing bodies across 750 jurisdictions, with 250 subject matter experts helping to review the material.
The distinction matters for a Canadian legal team advising a client entering a second market. Two jurisdictions may impose similar obligations, yet publish different guidance on the records a firm should keep to demonstrate compliance.
Guidance was where CUBE reported the largest gap in its own benchmark. Its system retrieved six to 17 times as much material across guidance, codes and supervisory documents as the other AI models it tested. It found three to four times as many regulations that CUBE classified as essential.
The integration follows Thomson Reuters’ recent announcement of a Multinational Profile for CoCounsel Legal. The company identified Canada as an early market for the feature, which lets lawyers compare requirements across more than 100 countries and territories and trace findings back to their sources.
