Research + agentic AI (cloud)
EdgeLex vs. CoCounsel (Thomson Reuters)
CoCounsel grounds in authoritative Westlaw and Practical Law content — a genuine strength. EdgeLex differs on deployment and operational breadth.
Thomson Reuters CoCounsel is a leading research-and-drafting AI, grounded in authoritative Westlaw and Practical Law content, with agentic workflows and strong security. Its grounding against proprietary published law is a real strength EdgeLex does not replicate.
CoCounsel is cloud-only and focused on research, drafting, and document analysis — not matter management, billing and trust, court-rule deadlines, intake, or self-hosted email. EdgeLex is a complete platform you can self-host, run in your private cloud, or use in our cloud, with local-model support.
The two are complementary in shape: CoCounsel grounds in Thomson Reuters' content library; EdgeLex grounds in your firm's own documents, emails, court rules, and a firm-curated case library, under default-deny governance and your choice of deployment.
