Thomson Reuters AI for legal, tax, audit, and compliance work.
概要
CoCounsel is Thomson Reuters' AI for legal, tax, audit, compliance, and drafting work, grounded in its content and connected to Westlaw, Practical Law, Checkpoint, Microsoft 365, and document-management partners. The company says customer content and prompts are not used to train CoCounsel or the underlying models, and that OpenAI and Google calls use zero-retention APIs.

r/biglawの同じコメントは、日常の起草でHarveyの席を置き換えた小さめの道具の一つとしてCoCounselを挙げています。
そのスレッドにCoCounselだけの失敗は読んでいません。共通点は、人が草稿をまだ確認する、ということです。
