Thomson Reuters CTO Joel Hron outlined an expanded product integration with KM (Knowledge Management) firm DeepJudge, which builds upon a partnership initiated in October 2025. The collaboration now features a full technical integration allowing lawyers to directly use DeepJudge’s search capabilities within Thomson Reuters' CoCounsel agent interface. This integration is currently accessible across Westlaw Advantage, the web application, and the Practical Law Dynamic Tool Set. By linking DeepJudge’s search functionality with the CoCounsel agent, legal professionals can locate internal firm documents and immediately process them using CoCounsel’s research, analysis, and drafting tools without needing to download or re-upload files. The system maintains existing user permissions and ethical walls while automating sign-in via current DeepJudge credentials.

The companies are also moving toward deeper technical integration using the MCP (Model Context Protocol, an open standard for connecting AI assistants to data sources). Hron emphasized that while deeper agentic workflows (AI systems that autonomously perform multi-step tasks) increase overall token consumption, Thomson Reuters focuses on optimizing the context fed to models to improve accuracy and trustworthiness. By surfacing relevant internal knowledge through DeepJudge, the CoCounsel platform aims to ground its outputs in better organizational data. Hron stated that the current priority remains maximizing the reliability and quality of work products for law firms rather than strictly minimizing token costs. Future roadmap plans involve further expanding these integrations to enhance how firms combine internal precedent with external authority.
