What it is
Overview
A legal-specific AI assistant that searches case law, analyzes briefs, and answers legal questions using what the vendor describes as expert-validated sources. Built for attorneys, legal researchers, and solo practitioners who need AI responses anchored in legal precedent rather than general knowledge. The tool integrates with existing legal workflow systems like Westlaw and Clio. Review volume is zero, so user patterns remain unverified.

Questions
Frequently asked
What is CoCounsel?
CoCounsel is an AI tool designed specifically for legal, tax, audit, and compliance professionals who need defensible answers they can verify and defend. It delivers what Thomson Reuters calls 'Fiduciary-Grade AI' by grounding all responses in authoritative content from sources like Westlaw, Practical Law, and Checkpoint rather than general internet sources.
How is CoCounsel different from general AI tools like ChatGPT?
Unlike general-purpose AI that prioritizes speed, CoCounsel focuses on accuracy, verifiability, and defensibility for high-stakes professional work. It draws exclusively from Thomson Reuters' verified professional content databases and provides transparent sourcing for every output, allowing professionals to defend their work to clients, courts, or regulatory bodies.
What can CoCounsel help me do?
CoCounsel can conduct legal research using authoritative sources, draft compliance documents and regulatory filings, perform audit procedures and risk assessments, analyze tax regulations, review and summarize legal documents with citations, and generate defensible professional reports with transparent reasoning.
Is my data secure when using CoCounsel?
Yes, CoCounsel implements enterprise-grade privacy and security safeguards designed for sensitive professional work. All data processing occurs under Thomson Reuters' identity rather than individual customer identification, they maintain zero-retention API calls with third-party AI providers, and customer data is never used to train underlying language models.
Does CoCounsel integrate with my existing workflow tools?
Yes, CoCounsel integrates directly with existing professional workflows through connections to Microsoft 365, Westlaw, Practical Law, Checkpoint, and major document management systems. This allows you to use the tool within your current work environment without disrupting established processes.
How does CoCounsel ensure the accuracy of its responses?
CoCounsel ensures accuracy through multiple layers: it exclusively uses Thomson Reuters' proprietary, authoritative content databases, provides transparent sourcing and reasoning for every output, and has subject-matter experts who continuously validate the AI's responses in real-time to maintain domain-specific accuracy and professional judgment.
Who uses CoCounsel?
CoCounsel serves over one million users and is designed for legal, tax, audit, and compliance professionals who have fiduciary duties and need AI assistance that meets professional standards. It's built for professionals who must be able to defend and verify their work to clients, courts, or regulatory bodies.
