Casetext (Thomson Reuters) — CoCounsel AI Legal Assistant

Overview

Casetext, founded in 2013, is a legal AI pioneer best known for CoCounsel, an AI assistant for research, drafting, and document analysis. In August 2023, Casetext was acquired by Thomson Reuters for $650M; the platform is now marketed as CoCounsel across legal, tax, and audit use cases. The core legal product is available via [Casetext](https://casetext.com) and Thomson Reuters’ [CoCounsel overview](https://www.thomsonreuters.com/en/cocounsel) and [CoCounsel Legal](https://legal.thomsonreuters.com/en/products/cocounsel-legal) pages.

CoCounsel integrates Thomson Reuters’ premium content (e.g., Westlaw, Practical Law) with firm documents to deliver deep research, first drafts with citations, and document analysis—now extended with Microsoft Word drafting and sector-specific versions for tax and audit.
