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
Eve
Eve builds EveOS for plaintiff-side firms in personal injury, employment, medical malpractice, workers' compensation and Social Security disability. It runs intake, structures medical records, drafts demands and discovery, audits open matters nightly, and answers plain-English questions about the firm's own numbers.
- Built for one side of specific practice areas, so the workflow assumptions are correct rather than generic
- Medical chronology and nightly re-auditing target the real bottleneck in plaintiff work
- Security posture answers the questions a firm must ask: SOC 2 Type 2, HIPAA, US residency, no shared-model training
- Intake covering after-hours calls addresses a leak that costs plaintiff firms real cases
- Useless outside plaintiff practice — defence-side, transactional, family and immigration firms cannot adapt it
- Settlement and revenue improvements are customer-reported with no methodology, and outcome effects are close to unprovable
- No trial and no published pricing, so evaluation requires a sales process and committed firm time
