Third-generation Lexis+ AI features highly personalized Protégé Legal AI Assistant, driven by customer feedback as part of US Commercial Preview program

NEW YORK – LexisNexis^® Legal & Professional, a leading global provider of AI-powered analytics and decision tools, today announced the US Commercial Preview program for LexisNexis Protégé^™ Legal AI Assistant on the third generation of Lexis+ AI^®. Protégé^™ marks a substantial leap forward in personalized generative AI that will transform legal work, with personalization choices controlled by the customer. Customer-driven innovation is core to the company’s product development, and LexisNexis is taking a customer-first approach to the generative AI technology journey as well. LexisNexis is teaming up with leading Am Law 100 firms as part of the US Commercial Preview program to tap into their continuous feedback.

Protégé builds on Lexis+ AI technology and market leadership. Lexis+ AI is commercially available in the US, US law schools, Canada, the UK, France, and Australia. Lexis+ AI is the only major legal generative AI solution used in law school curricula today, available in 100 percent of US law schools. Near term, Lexis+ AI international market expansion plans include Austria, Hong Kong, New Zealand, Malaysia, and Singapore. Lexis+ AI users worldwide have generated millions of prompts and conversations, forming one of the world’s largest sets of user experience data in legal generative AI.

“Our customers are at the forefront of co-developing legal generative AI technology with us by testing, providing feedback, and adopting Lexis+ AI,” said Sean Fitzpatrick, CEO of LexisNexis North America, UK and Ireland. “Customers guide our vision. They are ready to progress from a Legal AI Assistant built for everyone, to the next phase – a Legal AI Assistant uniquely customized and tailored for each individual legal professional.”

LexisNexis Protégé is a private, trusted Legal AI Assistant, unique to each legal professional. Personalization choices are controlled by the user or their organization – creating a set of choices to optimize the user’s generative AI experience. Protégé will support legal professionals in making informed decisions faster, generating outstanding work quality, and freeing up time to focus on efforts that drive economic value for their clients and organizations:

• Protégé is dedicated to understanding each user’s legal work needs, continuously learning and improving, and anticipating new ways to support them. Last month, LexisNexis acquired Henchman, a Belgium-based company, to catalyze its shift to personalized generative AI. Henchman’s advanced technology provides deeper access to law firms’ internal work product. Its technology enriches data from law firms’ Document Management Systems (DMS), enabling users to quickly mine internal repositories and extract and interact with key insights. Integrating Henchman^® DMS technology with trusted LexisNexis^® content using its proprietary Retrieval Augmented Generation (RAG) 2.0 platform improves answer quality and accelerates personalized generative AI.
• Protégé personalization capabilities fuel a wide set of new AI-enabled tasks. Protégé knows specifics about each user like workflow preferences, daily task requirements, firm standards, teamwork and communication styles, legal areas of specialization, and past work product. It proactively suggests subscribed LexisNexis products to provide insights and analytics. Protégé will become increasingly versatile, flexible, and useful as new technologies are incorporated like voice and multi-media processing.
• Protégé is ubiquitous across the LexisNexis AI-powered ecosystem––from the company’s portfolio of products to Microsoft 365 for Microsoft Word, Outlook, Teams, and Copilot. Protégé seamlessly works alongside the user, whether in a LexisNexis solution or third-party application like Microsoft, to reduce application switching time, accelerate efficiency, and meet the user where they work.
• The Protégé core framework integrates safety, security, and Privacy by Design principles. This ensures that interactions are backed by state-of-the-art security and privacy technology to keep data and user information highly secure.

In Q3 and Q4 2024, the Protégé personalization journey begins for users with functionality that:  

• Knows my work and leverages my own work product – provides searchable internal firm data combined with AI for deep insights, enables batch upload capabilities and performs AI tasks, and analyzes my documents and provides contextual recommendations.
• Knows my workflow and meets me where I work – integrates across LexisNexis solutions and Microsoft 365 and provides Shepard’s^® insights within conversations.
• Knows my tasks and supports a wide range of new use cases – supports daily task organization, client meeting deliverables, and deposition preparation. Protégé builds timelines, conducts AI code compare, initiates statutory horizon scanning, enables document upload and analysis, drafts full documents, and conducts intelligent legal research.
• Knows me and supports complex conversations – provides personalized responses based on user profiles and past behaviors, engages in sophisticated dialogue with clarifying questions and recommendations, and gives responses informed by subscribed LexisNexis products.
• Knows how to harness innovative, new technology to uniquely support me (2025) – includes answering prompts by voice, multimedia processing across text, image, video and audio, and news horizon scanning to identify breaking opportunities and risks.
