CoCounsel Legal is Thomson Reuters' AI assistant for lawyers. From a single plain-language request it builds a step-by-step plan, reasons through the matter, and delivers research, analysis and drafts with linked citations. Its answers draw on Westlaw content, Practical Law guidance and an organization's own documents. Features include Workspaces that keep matter context together, Westlaw Brief Builder for litigation briefs, and Tabular Analysis that reviews up to 10,000 documents against 100 questions in one table. Demos are free to request, and plans can be viewed through Thomson Reuters.
CoCounsel Legal is meant for litigators, transactional attorneys, in-house counsel and small firm owners who spend hours on research, document review and drafting. Associates use it to get a researched starting point with sources they can verify, while partners can inspect the reasoning. Corporate legal departments apply it to contract and compliance questions across large document sets. Firms using iManage, NetDocuments, SharePoint, HighQ, Box or Litify can connect existing content, and lawyers can work from Microsoft Word, Outlook and Teams.
A litigator can frame an issue, build an argument structure and produce a brief grounded in Westlaw authority, then verify every citation before filing. A deal team can review thousands of agreements against a list of questions and filter the table to spot risky terms. Corporate counsel can return to a saved Workspace and continue a matter without starting over. A small firm can convert a client request into a polished draft using prior-matter context. Surveyed users report improved research and drafting quality and an average 33 percent reduction in time spent on document review, research and drafting.
