LegiMatch vs CoCounsel
LegiMatch vs CoCounsel: AI legal research compared
CoCounsel Legal is a broad AI assistant from Thomson Reuters: deep research on Westlaw content, document review and drafting. LegiMatch is a research tool with one focus: finding decisions with facts like yours and showing why each one matched. Here's how they differ.
Answers vs ranked cases
CoCounsel produces research reports and drafts with citations to Westlaw sources. LegiMatch returns a ranked list of real decisions, up to 100 per matter, each with a match score broken down by facts, issues, statutes, jurisdiction and recency, so you can judge relevance yourself.
Beyond research
CoCounsel also reviews large document sets and helps draft. LegiMatch doesn't draft or review discovery; it does check every citation in a brief and builds a table of authorities.
Price and contract
CoCounsel plans are quoted per firm and often bundled with Westlaw. LegiMatch publishes its prices and runs month to month.
