CoCounsel is Thomson Reuters' AI assistant for legal and tax professionals, sold as CoCounsel Legal, CoCounsel Tax and CoCounsel Audit & Accounting. The legal product answers research questions from Westlaw and Practical Law content with linked citations, drafts from a request, and reviews document sets — up to 10,000 documents against 100 questions in a filterable table — using multi-step agentic plans the user can inspect before they run. It works in the browser and inside Word, Outlook and Teams, connects to iManage, NetDocuments, SharePoint and other document systems, and is exposed to Claude through an MCP server. It began as Casetext's product and was acquired by Thomson Reuters; pricing is by quote only.

Pros & cons of CoCounsel
CoCounsel is the safe choice for a firm already paying Thomson Reuters: research answers come with Westlaw citations, review tables trace every cell to a source, and it lives inside Word and the document-management systems lawyers already use. It is not a product you can try or price from the website — every number comes from a sales call — and the moat is the content licence, so a firm on Lexis gets far less from it.
Pros
- Research grounded in Westlaw and Practical Law content with linked citations
- Tabular document review scales to 10,000 documents against 100 questions
- Works inside Word, Outlook and Teams and connects to iManage, NetDocuments and SharePoint
- SOC 2 and ISO 42001 certifications and a stated no-training-on-customer-data policy
Cons
- No public pricing and no free trial on the product pages
- Value depends on an existing Thomson Reuters content subscription
- Reported outcome figures come from a vendor-commissioned Forrester study
Best for
- Law firms and legal departments with Westlaw or Practical Law subscriptions
- Litigation and transactional teams reviewing large document sets against fixed questions
- Tax and accounting practices on Checkpoint content
Not for
- Solo practitioners or small firms wanting a self-serve price and a trial
- Teams whose primary research platform is Lexis or an open corpus
Watch out: The research grounding is the Westlaw licence, so the real cost is CoCounsel plus the content subscription; price both before comparing against Harvey or Lexis+ AI.
