# CoCounselの料金・機能・代替（2026）

CoCounselの開始価格は Not published です。下の製品メモは、ベンダーが公開している料金のまま記しています。

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.

## 料金

The CoCounsel product page opened does not list a dollar price or a free trial. A separate Thomson Reuters sales page, seen in search but not opened, says online pricing is available only for new law-firm customers with up to 10 attorneys. Last checked 5 October 2026.
