Latest Lexis+ AI enhancements make legal AI Assistant more efficient, effective and personalized for all existing customers  

NEW YORK – LexisNexis Legal & Professional®, a leading global provider of information and analytics, is unveiling its second-generation legal generative AI Assistant on the industry-leading Lexis+ AI™. Utilizing continuous user feedback, the next-level AI Assistant delivers an increasingly personalized experience to support legal professionals in making informed decisions faster, generating outstanding work, and freeing up time to focus on efforts that drive economic value. All existing Lexis+ AI customers will have access to the enhanced AI Assistant.

These enhancements represent another milestone in the company’s legal generative AI leadership, building on the commercial introduction of Lexis+ AI in October 2023. Grounded in the world’s largest repository of up-to-date, exclusive legal content from LexisNexis, Lexis+ AI enables conversational search, insightful summarization, intelligent legal drafting, and document upload and analysis capabilities in a seamless user experience.

Recently launched and upcoming enhancements include: 

  • Faster Delivery of Results – AI-generated answers will now be delivered word-by-word for a faster, more conversational experience. The AI Assistant returns trusted results backed by verifiable authority two times faster than the nearest competitor.
  • Enhanced Multi-Turn Conversation Capability – Contextual prompt conversations with the AI Assistant have been increased from a limit of five interactions to ten, helping users gain deeper insights and refine generative AI answers.
  • Conversational Guidance for Drafting – Providing tailored, step-by-step recommendations that anticipate questions and guide users to leverage answers directly in drafting work including emails, letters, arguments, clauses, and memos. 
  • Added Delivery Options– Expanding Lexis+ AI capabilities with new delivery options for conversations including Email, Download, and Print.  
  • AI-Generated Statute Summaries – Providing the first legal market generative AI-powered summaries across U.S. federal and state statutes. Also available to the public via the LexisNexis U.S. Voting Laws & Legislation Center as a part of the company’s work to support transparency of law. 
  • Increased Document Upload Capacity – Enabling users to analyze and summarize larger documents, now up to 400,000 characters per request (approximately 150 pages per document).
  • Improved User Experience – Refining the user experience with improved readability, ease-of-use, and aesthetic updates, including support to easily deliver and share Lexis+ AI output.

All features will be available to customers by early May. Customers are responding positively to enhancements, with 91% of users reporting Lexis+ AI is easy to use – a 5-point increase since October 2023. The product enhancements extend the company’s longstanding leadership in legal AI and advance its vision for leveraging generative AI to transform legal work.
