CoCounsel

CoCounsel is an AI assistant from Thomson Reuters built for professional work in law, tax, accounting and risk. It combines generative AI with the publisher's content, with the aim of giving answers that rest on authoritative sources, and it is sold with a focus on security for professional firms.

For legal teams, the site lists use cases such as legal research and advisory, drafting, review and analysis, due diligence and compliance, and document and matter management. Practice areas shown include corporate and commercial law, mergers and acquisitions, labor and employment, family law, personal injury, civil litigation and criminal defense. It also addresses tax and trade professionals and risk and fraud professionals, covering tasks such as financial close and investigations.

Audiences named on the site include law firms, businesses, tax, audit and accounting firms, and government, as well as general counsel, chief financial officers and chief risk officers. CoCounsel is a hosted commercial product that works alongside Westlaw AI, and customers purchase through Thomson Reuters.
