2 min readSources: Artificial Lawyer

Thomson Reuters made the DeepJudge-CoCounsel AI integration generally available on June 17, 2026.

Why it matters: This integration consolidates firm-specific precedents, Westlaw research, and Practical Law standards in one AI platform, streamlining legal workflows and reducing research time.

  • Thomson Reuters announced the general availability of DeepJudge integration in CoCounsel on June 17, 2026.
  • Users can access firm-specific legal documents, Westlaw research, and Practical Law content within CoCounsel.
  • DeepJudge is a Swiss company focusing on legal knowledge management technologies.
  • This launch follows a May 2026 enhancement where Anthropic's Claude AI was integrated into CoCounsel.

On June 17, 2026, Thomson Reuters announced the general availability of the DeepJudge integration for CoCounsel, its AI-assisted legal research and workflow platform. The integration allows lawyers to combine multiple legal knowledge sources in a unified AI-driven environment.

Legal professionals now can access firm-specific work product and precedents alongside Westlaw’s extensive legal research and Practical Law’s market content within CoCounsel. This consolidation aims to reduce switching between platforms and deliver a more comprehensive view of cases.

DeepJudge, headquartered in Switzerland, develops specialized knowledge management tools tailored to legal professionals. Its technology underpins this integration to enhance AI’s understanding of firm-specific data and broader legal resources.

The product builds on Thomson Reuters’ ongoing efforts to enhance CoCounsel's AI capabilities. In May 2026, the company integrated Anthropic's Claude, a large language model, into CoCounsel to improve legal research and document review accuracy, according to Legaltech News. These developments collectively aim to provide reliable, firm-tailored AI tools that fit legal workflows.

By merging firm-specific insights with established research databases, the integration supports more informed decision-making during case assessments and document reviews. Legal professionals can expect faster access to relevant materials without compromising accuracy.

By the numbers:

  • June 17, 2026 — Date DeepJudge-CoCounsel AI integration became generally available
  • May 2026 — Anthropic's Claude AI model integrated into CoCounsel
  • 3 key resources combined — Firm-specific work product, Westlaw research, Practical Law content

Yes, but: While the integration offers a consolidated AI-driven workflow, adoption depends on firms customizing DeepJudge for their specific data contexts, which may require training and adjustment.

What's next: Thomson Reuters plans to continue expanding CoCounsel’s AI integrations, potentially adding more specialized legal data sources to enhance firm-specific research capabilities.
