LexisNexis+ AI PromptLexisNexis Legal & Professional has announced that its Lexis+ AI generative AI solution is now available in the UK under commercial preview. The solution became generally available in the USA last October after a successful five-month commercial preview. LexisNexis will also launch a commercial preview of the product in Canada later today.

The company is already partnering with several firms on the commercial preview and named some of them during the announcement. Eversheds Sutherland (International), Macfarlanes, Pinsent Masons and CMS UK have already joined the preview program.

Rachel Broquard, Service Excellence Partner at Eversheds Sutherland (International), noted, “We are supporting the research and development of generative AI across the industry. LexisNexis is a key content provider, so its roadmap will be closely watched as many firms’ on-ramp to generative AI-based research.”

AN AI Search to save time

In summary, the features provide an enhanced AI Search that interacts, summarises drafts and can also review and compare a legal department’s own documents. Where this capability differs from other legal AI tech was summarised by Jeff Pfeifer, Chief Product Officer, Canada, Ireland, UK and USA.

Pfiefer noted, “One of the key elements that differentiates Lexus+ AI and makes it so powerful is the underlying content on which answers are grounded. From primary law to secondary sources, encyclopaedias like Halsbury’s and PSL practical guidance collection, we’re adding more and more content all the time.”

The new capabilities are included within Lexis+, which has enabled a rapid adoption of the platform in the US already. Pfeifer added, “We’re seeing substantial interest from all market segments. And by that, I mean large law firms, the government, small firms, in in-house legal departments. But notably, I would call out small law firms, in particular, seem to be very focused on using and leveraging the technology to improve work efficiencies within their practice.”

What can Lexis+ AI do?

Amongst the capabilities that LexisNexis demonstrates are four use cases during a presentation of the solution.

Conversational search

Conversational search enables legal teams to ask questions in natural language to shorten the often time-consuming legal research process. The capability enables the user to ask a question such as “What potential age or disability discrimination could be brought under the Equality Act 2010 by a 53-year-old employee with diabetes.”

The response is comprehensive and detailed the potential claims with references and links to the relevant law, which are available on the LexisNexis platform. It extends the query with responses for age discrimination and harassment and also provides citations from case law.

The user can either then pose an iterative question based on the previous response to dive deeper into the subject or request the AI to provide content such as an email or instructions as to how to file against a regulation.

Enhanced summarisation

Enhanced provides a custom summary of legal documents to speed up and guide insightful analysis. For example, a lawyer might ask the system to summarise a historical case without having to wade through the full document, though that is always available on the LexisNexis platform.

The summarisation will provide details such as:

  • Document type
  • Legal issues covered
  • Key legal holdings
  • Jurisdiction
  • Material facts
  • Controlling law
  • Court rationale
  • Procedural outcome
  • Parties and how the case affects them

Document drafting

Generative document drafting helps the lawyer through the drafting process. They can request the AI to generate a legal clause for something a specific as a limitation of liability clause which is pro party B in a supply of services agreement.

If the response is too long or not in the correct tone, the user can ask for the tone to be changed or for the generation of a simpler, more concise clause. The clause created will have reference links to the sources, which can then be looked at.

Document upload capabilities

The document upload capability is a new feature that was requested by the early adopters in the US. It enables users to upload up to ten documents for comparison by the generative AI tool and provide insights on the difference, for example. The documents are only stored within the current session and are never loaded into the data repository for the platform.

The platform

LexisNexis+ AI is built using the RELX Responsible AI Principles and uses global cloud providers such as Microsoft Azure and AWS to ensure that data is protected and kept private, with state-of-the-art security.

Gerry Duffy, MD of LexisNexis UK, said, “We’re thrilled to bring this transformative technology to our UK customers. The Lexis+ AI solution is a proven first-of-its-kind tool for lawyers and will dramatically improve the speed, quality, and effectiveness of their practice and business. We have taken a customer-first approach to all our innovation, research and product development.”

Jeff Reihl, Chief Technology Officer, LexisNexis Legal & Professional, commented, “LexisNexis has been leveraging artificial intelligence technology, including natural language processing and large language models, in our legal solutions for years, and we’ve been using generative AI in our research and development labs for more than two years.

“As a leader in legal AI and analytics, we are well positioned to serve as firms’ trusted partner in launching professional-grade, legal generative AI tools.”

Enterprise Times: What does this mean?

The localisation of this feature and the fact that it will become available to legal teams in the UK and Canada, initially in commercial preview and then generally available, is exciting. Based on the initial feedback from the US, it should save considerable time for UK lawyers.

The question is whether legal teams will trust the generative AI. That is something that will develop over time. However, the LexisNexis+ AI gives lawyers the ability to quickly validate the information provided. The only question is whether it missed anything that human intuition might pick up.

In a recent survey, 52% of respondents from large law firms and 59% from in house counsel, believing that generative AI tools will significantly transform the practice of law.  With solutions like this now available that percentage will likely soar by the end of the year. Pfeifer also revealed that commercial preview would also be available in Australia and France shortly.
