Casetext CoCounsel
AI legal research and litigation intelligence
An AI legal assistant that performs comprehensive case law research, document review, deposition preparation, and contract analysis for trial attorneys.
Casetext (now part of Thomson Reuters) developed CoCounsel as the first comprehensive generative AI legal assistant built specifically for practicing trial attorneys and corporate litigators. Powered by advanced LLMs and grounded in authoritative primary law databases, CoCounsel performs reliable case law research, document review, and brief analysis.
Unlike general AI chatbots that can invent fictitious case citations, CoCounsel searches verified statutory codes and judicial opinions, linking every sentence directly to real legal authority. Attorneys can upload thousands of discovery documents and ask specific factual questions to uncover key evidence and construct precise chronological timelines.
During litigation prep, CoCounsel analyzes witness testimony to suggest cross-examination questions and identify contradictions. For law firms and corporate litigation teams, it delivers a formidable research advantage while drastically reducing billable research hours.
