CoCounsel

Best for legal research with Thomson Reuters backing

CoCounsel is a Thomson Reuters product combining GPT-4 with Thomson Reuters' vast legal content including Westlaw, providing access to comprehensive case law, statutes, regulations, and secondary sources. Legal research capabilities include finding relevant cases, analyzing precedent strength, identifying distinguishing factors, and synthesizing holdings across multiple jurisdictions to support legal arguments. Document review features analyze thousands of documents in litigation or due diligence contexts, identifying key documents, extracting relevant facts, and organizing information by issue or timeline. Deposition preparation functionality reviews case documents and suggests questions based on facts, inconsistencies, and legal theories, helping attorneys prepare more effective examinations. Contract analysis reviews agreements to identify key terms, risks, obligations, and non-standard provisions, creating summaries that highlight important business and legal terms. Timeline creation automatically generates chronologies from case documents by extracting dates, events, and parties, organizing complex fact patterns into understandable sequences. Case law summarization provides concise summaries of judicial opinions, extracting holdings, reasoning, and procedural history without requiring attorneys to read full opinions for initial assessment.
