CoCounsel

What is CoCounsel?

CoCounsel is an AI legal assistant from Thomson Reuters that helps lawyers complete legal research, drafting, and document analysis with speed and precision.

Originally developed by Casetext, which Thomson Reuters acquired, CoCounsel has become a widely adopted professional legal AI tool serving large numbers of professionals across many countries.

It is built to handle common, time-consuming legal tasks: reviewing and summarizing documents, extracting key information from large sets of files, drafting and analyzing contracts, preparing for depositions, and answering legal research questions grounded in authoritative content.

Because it connects to Thomson Reuters' legal databases and editorial materials, its answers are anchored in primary law and professional secondary sources, which is important for accuracy and citation reliability in professional practice.

Typical users include law firms, in-house legal departments, and corporate compliance teams that need to process high volumes of legal work. Strengths include integration with trusted Thomson Reuters content, broad task coverage across research and drafting, and enterprise-grade security and support.

Weaknesses are that, like all legal AI, its output must be verified by a qualified attorney, and it is an enterprise product priced accordingly rather than aimed at individual consumers.

CoCounsel is sold through subscription and enterprise licensing rather than a free consumer tier, and it is typically adopted by firms and departments alongside their existing Thomson Reuters research subscriptions. Pricing changes often, so check the official site for current plans.

CoCounsel's core capabilities include AI-assisted legal research grounded in professional content, Document review and summarization at scale, Contract drafting and analysis, Information extraction across large file sets and Deposition preparation support.
