CoCounsel

CoCounsel is Thomson Reuters' flagship AI legal product — built on GPT-4 and deeply integrated with Westlaw (the industry's leading legal research database) and the firm's decades of legal content. Thomson Reuters acquired Casetext (the original CoCounsel developer) in 2023 for $650 million.

## Document Review

CoCounsel reads and analyzes large document sets at speed no human team can match. For discovery (civil litigation requiring review of thousands of documents), CoCounsel can review and classify an entire document population in hours. Lawyers specify what they're looking for (specific issues, dates, parties, communications), and CoCounsel identifies relevant documents and summarizes findings.

## Contract Analysis

Upload any contract and ask CoCounsel specific questions: "What are the indemnification obligations?" "Does this agreement have a change of control clause? What does it require?" "Are there any unusual termination rights?" CoCounsel reads the contract and answers with page references and direct quotes.

## Legal Research with Westlaw Integration

CoCounsel integrates with Westlaw to perform comprehensive legal research — not just finding relevant cases but summarizing holdings, synthesizing positions across multiple authorities, and identifying split circuits or evolving precedent. Research that takes a junior associate hours takes CoCounsel minutes.

## Deposition Preparation

Upload a deposition transcript and witness documents, and ask CoCounsel to identify key testimony, inconsistencies with documents, and areas for follow-up questions. It generates deposition outlines based on the factual record.

## Timeline of Events

Feed CoCounsel a document set and ask it to construct a timeline of events — it extracts dates, parties, and actions from across thousands of documents to build a chronological narrative.

## Pricing

CoCounsel is included with Westlaw Precision subscriptions and available as an add-on. Westlaw Precision starts at approximately $500-800/month for small firms. Enterprise pricing for large law firms is custom.
