CoCounsel

It allows users to ask complex legal research questions in natural language, review large document sets for specific information, analyze contracts against checklists or for specific clauses, prepare deposition outlines by analyzing transcripts, draft initial legal memos or correspondence, and summarize documents. It emphasizes reliability by often providing citations and links back to source material within the Thomson Reuters ecosystem (Westlaw, Practical Law). It's designed to augment lawyers' skills across various practice areas.
