On Tuesday, Thomson Reuters announced the U.K. launch of CoCounsel Core, a stand-alone version of its legal artificial intelligence assistant accessible without a Westlaw subscription­. The company also announced the upcoming U.K. availability of AI-Assisted Research on Westlaw Edge UK, a generative AI update to its legal research platform that will be available "in the coming weeks," according to a news release.

CoCounsel was developed by legal research company Casetext, which Thomson Reuters acquired for $650 million last August. Thomson Reuters initially announced CoCounsel Core for the U.S. market last November, alongside a broader integration of CoCounsel throughout its suite of tools. The legal AI assistant allows users to leverage generative AI to perform a number of tasks, from document drafting and summarization to data extraction, search and research.

The expansion of CoCounsel Core to the U.K. comes just months after the company also officially announced the tool's availability in Canada and Australia.
