The UK Gets Access To Thomson Reuters’ Gen AI Product CoCounsel Core and Soon To Its AI-Assisted Research on Westlaw Edge

Thomson Reuters today brings its generative AI legal assistant CoCounsel Core to the United Kingdom, following its initial rollout in the United States and expansion last month into Australia and Canada.

The company also said that its AI-Assisted Research product, launched in November within Westlaw Edge for the U.S., would be available on Westlaw Edge UK within weeks.

CoCounsel Core is the generative AI product originally launched one year ago this month by the legal technology company Casetext. Following its acquisition of Casetext in June 2023, TR announced in November that it would integrate CoCounsel across multiple products, while also continuing to sell it as a standalone product, renamed CoCounsel Core.

Last month, TR expanded availability of CoCounsel Core to Australia and Canada, and with today’s announcement, it becomes generally available in the UK, where TR says it is already being used by multiple law firms.

“In just over a year since CoCounsel debuted, our goal of transforming how people work is becoming a reality in more places across the world, more quickly than we could have imagined,” said Jake Heller, cofounder and former CEO of Casetext and now head of the CoCounsel product at TR. “It’s proof that the Thomson Reuters build, buy and partner strategy is accelerating how quickly we can deliver generative AI solutions to the professionals who rely on us.”

CoCounsel Core provides customers with eight core generative AI-powered legal skills: Prepare for a Deposition, Draft Correspondence, Search a Database, Review Documents, Summarize a Document, Extract Contract Data, Contract Policy Compliance and Timeline.

Casetext launched CoCounsel on March 1, 2023, helping to fuel a frenzy of legal tech companies developing generative AI products. To mark that one-year milestone, it recently published the CoCounsel Index of facts and figures about the product’s growth.
