LONDON, 12 March 2024 – Thomson Reuters (TSX/NYSE:TRI), a global content and technology company, today announced the UK launch of its generative AI legal assistant, CoCounsel Core. Continuing the rapid execution of Thomson Reuters AI technology strategy, UK availability of this leading generative AI legal assistant quickly follows launches in Canada, Australia, and the United States.

The company also announced that AI-Assisted Research on Westlaw Edge UK will be available in the coming weeks. The generative AI legal research solution will help legal professionals get better, faster answers to complex research questions grounded in trusted Westlaw content. Together, they will lead the transformation of the UKs legal profession.

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

“This latest international launch of CoCounsel Core is yet another significant milestone in our mission to empower legal professionals to do better work, more efficiently, for more clients,” said Jake Heller, head of Product, CoCounsel, Thomson Reuters. “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. 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.”

Designed with the technical controls and data governance to meet legal professionals’ ethical and confidentiality obligations, CoCounsel Core is the only professional-grade generative AI assistant built specifically for the practice of law. Together with AI-Assisted Research on Westlaw Edge UK, CoCounsel Core's capabilities constitute the industry’s most comprehensive set of generative AI skills, designed to help lawyers quickly gather deeper insights and deliver a better work product. No other suite of generative AI legal products offers this breadth of use, depth of content, and reliability of results. CoCounsel Core can save legal professionals as much as 60% of the time they spend on commonly executed tasks, freeing them for more high-value, strategic, and creative work.

CoCounsel Core is already being used by multiple UK law firms, including Addleshaw Goddard LLP and Linklaters LLP. Employing more the 1,600 lawyers in 19 offices worldwide, Addleshaw Goddard’s origins reach back to the UK’s first public record of solicitors, the Law List, in 1775. Linklaters is currently exploring use-cases for CoCounsel within its business. Linklaters has operated in the legal market for over 185 years, and is a leading global law firm, employing more than 3,100 lawyers in 31 offices across 21 countries.

"Generative AI has untold potential to support our lawyers and transform our client services now and in years to come." said Kerry Westland, partner and head of the Innovation Group at Addleshaw Goddard. "While researching and exploring over 100 generative AI solutions, CoCounsel stood out as a solution that could be highly effective for a range of use cases, including bulk document analysis. We are already applying CoCounsel in the work we are delivering for our clients, and it is exciting to see the value that this technology can bring. We are looking forward to seeing CoCounsel and Thomson Reuters other AI solutions working together, delivering a powerful suite of tools to our lawyers to enhance our delivery of legal services."

Foundational to these launches and product developments planned for 2024 is the Thomson Reuters Generative AI Platform, an overarching innovation resource that enables the company to quickly and easily launch new solutions by leveraging reusable components and bringing together content, AI, generative AI, and more, as the building blocks for future products.
