Thomson Reuters AI assistant for legal research, drafting, and document analysis

★ 4.5 / 5.0

Overview

CoCounsel is an AI legal assistant from Thomson Reuters that integrates directly with the trusted content of Westlaw. It is designed to help legal professionals work more efficiently by handling time-intensive tasks. The tool allows lawyers to ask complex legal questions in plain English and receive precise answers supported by citations to authoritative cases, statutes, and secondary sources. It also analyzes uploaded documents, such as contracts or deposition transcripts, to quickly surface relevant information, discrepancies, or specific clauses. Key features include its ability to draft legal documents from a simple prompt, conduct thorough document review for issues and facts, and prepare for depositions by generating comprehensive case summaries. Its answers are grounded in Westlaw’s vetted legal database, providing a reliable foundation for legal work. CoCounsel is built for practicing lawyers, in-house counsel, and legal support teams within law firms and corporate legal departments who need to enhance their productivity and accuracy. A clear use case is during case assessment, where an attorney can upload a set of discovery documents and ask CoCounsel to identify all mentions of a key witness and any related contractual obligations. Within minutes, the tool provides a synthesized report with pinpoint citations, saving hours of manual review. The main benefit is a significant reduction in the time spent on research and document analysis, allowing legal professionals to focus on higher-level strategy and client advisement.
