Thomson Reuters CoCounsel: GenAI Assistant for Professionals

CoCounsel is a professional-grade generative AI (GenAI) assistant from Thomson Reuters designed to transform how legal, tax, accounting, and risk professionals work. It integrates with Thomson Reuters trusted content and leading platforms to accelerate research, drafting, and advisory tasks while prioritizing data privacy, security, and compliance.

Key Value Proposition

  • Accelerates complex, high-value work by handling mundane tasks (research, drafting, document review) so professionals can focus on strategy and client outcomes.
  • Fully integrated with authoritative Thomson Reuters content (Westlaw Precision, Practical Law, etc.) and popular platforms (Microsoft 365) to streamline workflows.
  • Enterprise-grade security, data privacy controls, and governance designed for professional environments.

Core Capabilities

  • GenAI-assisted research: faster, accurate answers drawn from trusted sources.
  • Drafting assistance: end-to-end drafting support within familiar work environments.
  • Access to industry-leading content: integration with Westlaw Precision, Practical Law, and other Thomson Reuters products.
  • Cross-product consistency: a unified GenAI experience across the Thomson Reuters ecosystem and integrated platforms.
  • Security & privacy: data handling designed to prevent training on customer content and robust data protection measures.

How It Works

  1. Access and context: CoCounsel is accessible wherever you work within the Thomson Reuters ecosystem or via integrations (e.g., Microsoft 365).
  2. Leverage AI skills: professionals use specialized GenAI skills for drafting, research, and insights, supported by authoritative content.
  3. Output with governance: results are delivered with verifiable content provenance and compliance controls.

Safety, Privacy, and Compliance

  • Customizable retention policies at the organizational level; users can delete content/prompts anytime.
  • Data in transit protected by TLS 1.2; data at rest encrypted (AES-256).
