CoCounsel
CoCounsel Legal is Thomson Reuters' AI legal assistant. It reasons from Westlaw content, Practical Law guidance and your firm's own documents, producing cited research, analysis and drafts, with Workspaces, Westlaw Brief Builder and Tabular Analysis across up to 10,000 documents.
- Grounding in a licensed, edited corpus changes the failure mode from fabrication to judgement
- Linked citations reduce verification friction, which is what determines whether verification happens
- Content and AI come from the same publisher rather than two vendors pointing at each other
- Tabular Analysis brings consistency to questions asked across thousands of documents
- Most of the value depends on already licensing Westlaw and Practical Law
- Two of the three headline figures are agreement statistics, not measured outcomes
- Self-reported time savings are a weak basis for a business case

- The three-layer architecture is a coherent and honest description of the difficulty
- Public, distributed information analysed systematically is a legitimate advantage
- Serving compliance teams gives defenders the same visibility as adversaries
- Published numbers describe volume, not accuracy or outcomes
- Predictive claims are inherently hard to falsify from outside
- The same intelligence serves opposing interests, which buyers should understand
