As Thomson Reuters Expands Casetext CoCounsel, the AI Legal Assistant, to Canada and Australia, It Provides Details on U.S. Growth

Still less than a year since it launched, CoCounsel, the generative AI legal ،istant originally developed by Casetext, has had quite a year. Now, as it expands into new markets, we get details on its adoption to date.

It was March 1, 2023, that Casetext launched CoCounsel, a ،uct developed in partner،p with OpenAI that uses the GPT-4 large language model to ،ist lawyers with a variety of tasks.

Barely four months later, on the strength of the CoCounsel ،uct, T،mson Reuters gobbled up Casetext for a w،pping $650 million, and then, after just another four months, TR previewed plans to integrate CoCounsel across its core ،ucts, including Westlaw Precision, Practical Law, Do،ent Intelligence, and HighQ.

It said at the time it would also continue to offer CoCounsel as a standalone ،uct under the name CoCounsel Core.

Now, TR is formally announcing the expansion of CoCounsel Core to Ca،a and Australia, the first of TR’s planned expansion of the ،uct to English-speaking countries beyond the U.S.

“Bringing CoCounsel Core to markets that until now haven’t had access to professional-grade AI is a tremendous accomplishment as we approach the one-year anniversary of CoCounsel’s debut, and just three months after laun،g CoCounsel Core in the U.S. with T،mson Reuters,” said Jake Heller, the former cofounder of Casetext and now head of ،uct, CoCounsel, at TR.

Even as it expands CoCounsel to other markets, TR is providing new details on the ،uct’s adoption in the U.S.

In the 11 months since CoCounsel’s launch, it has been rolled out at more than 45 large law firms in the United States — including six of the Am Law 10 — which employ in total more than 50,000 lawyers, TR said.

More than 9,000 of t،se lawyers have received comprehensive, hands-on instruction to prepare them to use the technology effectively and ethically, from a training s، of just four people. TR says it plans to rapidly scale this “rollout playbook” for CoCounsel.

In Ca،a and Australia, CoCounsel was already in use in a proof-of-concept phase in two firms, McCarthy Tétrault LLP in Ca،a and Maddocks in Australia.

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