Casetext

Casetext, now part of Thomson Reuters CoCounsel, is an AI-powered legal assistant designed to support attorneys and legal professionals with complex research and drafting tasks. Built on large language models and integrated with authoritative legal content, it enables users to analyze case law, statutes, regulations, and secondary sources with high precision. The tool can conduct comprehensive legal research by answering nuanced legal questions, surfacing relevant authorities, and providing citations directly linked to source documents.

Key capabilities include automated case law review, brief and memo drafting, contract analysis, and document summarization. Users can upload pleadings, contracts, discovery documents, or other legal materials and receive structured analyses, issue spotting, and plain-language explanations. Casetext also helps verify arguments and citations by checking consistency with underlying authorities, reducing the risk of errors in filings.
