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
Solve Intelligence is an AI platform for patent work, covering application drafting, office action responses, invalidity and claim-mapping charts, freedom-to-operate reviews and portfolio analysis. It is used by over 700 in-house IP teams and law firms, with SOC 2 Type II and ISO 27001 certification and no training on customer data.
- Handles the specialised parts — figures, Markush claims, sequence listings — not just the prose
- Examiner statistics turn informal institutional knowledge into a queryable input
- Security posture is genuinely strong, including the newer ISO 42001 AI management standard
- Explicit no-training and zero-retention terms meet a threshold requirement in this field
- Contact-sales licensing with no self-serve route in
- Claim scope, where the commercial value sits, remains irreducibly a human judgement
- Prior art coverage cannot include applications unpublished for around eighteen months
