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
Ivo
Ivo is AI contract review for in-house legal teams. It applies redlines directly in Microsoft Word or Google Docs, evaluates agreements against your playbooks and historical contracts, benchmarks clauses by governing law and industry, and queries executed contracts in plain language.
- Works inside Word and Google Docs, where contract negotiation actually happens
- Applying redlines in the document removes the translation step a review report creates
- Reviewing against your playbook rather than a generic standard produces judgement rather than noise
- Deriving a playbook from executed contracts turns tacit institutional knowledge into something checkable
- No pricing published anywhere, so cost requires a sales process
- No accuracy or evaluation data for redlining, leaving your own testing as the only measure
- The population behind clause benchmarks is not disclosed, which changes what a benchmark means
