CoCounsel Legal review
A broad legal AI workspace for teams handling complex, high-volume matters.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
CoCounsel Legal is Thomson Reuters’ AI software for legal professionals, combining legal research, document analysis, drafting, and matter organization. It is designed for law firms, corporate legal departments, government users, and other professional legal teams. The product works from Westlaw content, Practical Law guidance, and an organization’s own documents, bringing research and internal matter materials into one experience. Its broad scope makes it a fit for teams that need more than a single-purpose document assistant.
Research and document work are the strongest parts of the offering. Deep Research provides step-by-step legal analysis with citations, while Litigation Document Analyzer handles uploaded legal documents. Tabular Analysis can evaluate up to 10,000 documents against up to 100 questions, and users can summarize, review, and compare documents with source citations. Legal drafting in Microsoft Word, Westlaw Brief Builder, and matter workspaces for documents, templates, conversations, and history extend the product from research into day-to-day legal work.
Its ecosystem fit is also significant for larger teams. CoCounsel Legal integrates with iManage, NetDocuments, SharePoint, HighQ, DeepJudge, Smokeball, Box, Litify, Microsoft Word, Microsoft Outlook, Microsoft Teams, Claude, and Supio. That range supports document management, Microsoft 365 workflows, and connected legal applications. The trade-off is a paid product with no free plan, and access is centered on professional legal use rather than lightweight individual research. Choose CoCounsel Legal for high-volume research, cited analysis, drafting, and matter organization across a larger team; choose a narrower tool if you need a simpler or lower-commitment workflow.
