Grounded on LexisNexis’ vast legal research and practical guidance content, following a successful preview, Lexis+ AI is now commercially available in the UK, delivering fully encrypted, secure interactions with accurate results in seconds.

LONDON, 13th June 2024 LexisNexis® Legal & Professional, a leading global provider of legal information and analytics, today announced that Lexis+ AI is now generally available for UK customers.  This follows the successful commercial launches of Lexis+ AI in both the USA and Australia.

Lexis+ AI delivers trusted results in a familiar, easy-to-use interface that combines the power of generative AI with proprietary search technology.  Lexis+ AI answers are grounded in one of the world’s largest repositories of reliable and exclusive legal content from LexisNexis, including primary, secondary, analytical content and expansive Practical Guidance modules.

Lexis+ AI provides direct links in its responses to the underlying citable authority.  This allows users to instantly validate results, reducing the risk of invented content, or hallucinations.  Lexis+ AI automatically checks all linked citations against LexisNexis’ content to ensure they are valid.

Developed with input from leading global law firms such as Macfarlanes, Eversheds Sutherland (International), Pinsent Masons and CMS UK, Lexis+ AI has been built to meet the day-to-day needs of lawyers.  Eleanor Windsor, Partner, Director of Knowledge Management, at Irwin Mitchell commented “we selected Lexis+ AI as it is the most advanced legally-trained AI solution on the market. It will enable us to maximise the value of the legal intelligence we already access from LexisNexis.”

The solution’s AI capabilities were built internally at LexisNexis with world-leading tech partnerships, enabling the company to rapidly introduce new features and technology and provide customers with a seamlessly integrated experience across the LexisNexis ecosystem.

Lexis+ AI features conversational search, intelligent legal drafting, insightful summarisation, and document upload capabilities, all supported by state-of-the-art encryption and privacy technology to keep sensitive data secure:

  • Conversational search simplifies complex and time-consuming legal research by enabling users to conversationally interact with Lexis+ AI, explore new insights, and ask for adjusted and refined output.
  • Document drafting instantly produces contract clauses and client communications from a simple user prompt.
  • Summarisation functionality delivers case summaries in seconds with more content and capabilities coming soon.
  • Document upload capabilities enable users to rapidly analyse, summarise and extract key insights from legal documents.

Lexis+ AI offers industry-leading data security and attention to privacy.  Uploaded documents are always purged at the end of each session and users can easily manage or delete their prompt conversation history.  The solution is continually improving, with LexisNexis legal subject matter experts regularly sampling hundreds of thousands of AI generated answers, to tune and educate the model.  LexisNexis employs over 2,000 technologists, data scientists and subject matter experts to develop, test, and validate its solutions and deliver comprehensive, accurate information.
“This is a pivotal moment in the history of the UK legal industry.  We are delighted to deliver a generative AI solution that will safely and securely enable our customers’ success,” said Gerry Duffy, Managing Director of LexisNexis UK.  “We have had unprecedented levels of interest in Lexis+ AI from our market and as of today, many of our customers will be enjoying the competitive advantage of having access to our rich and authoritative content combined with our leading AI technology”.

LexisNexis is responsibly developing legal AI solutions with human oversight.  LexisNexis, part of FTSE listed RELX, follows the RELX Responsible AI Principles.  These require the business to consider the real-world impact of its solutions on people and to take proactive action to prevent the creation or reinforcement of unfair bias.
