LexisNexis Introduces Protégé Personalized AI Assistant with Agentic AI, Making it Easier to Power Complex Legal Task Completion

Developed with customers leading the next wave of legal AI innovation, Protégé uses AI agents and generative AI, grounded in customer and LexisNexis content, for next-level productivity and outcomes
 

NEW YORK— LexisNexis^® Legal & Professional, a leading global provider of AI-powered analytics and decision tools, today announced the U.S. general availability of LexisNexis Protégé, a personalized AI assistant that intelligently powers productivity, drives next-level work quality, and enables legal and business professionals to unlock new economic value. Built with the highest levels of security, compliance, and privacy, Protégé is initially available within the Lexis+ AI^® legal workflow solution and Lexis^® Create+ for legal AI drafting in Microsoft Word and will soon be ubiquitous across LexisNexis products.

Developed responsibly with human oversight, agentic AI capabilities in Protégé can autonomously complete tasks based on user goals, including reviewing its own work and identifying areas where it can improve its own output. For the customer, this means simplified AI use, accelerated productivity, and enhanced value.

Leveraging proprietary agentic and generative AI technology from LexisNexis, Protégé can:

• Draft full, tailored transactional documents, as well as litigation motions, briefs, and complaints, and check its own work before turning them over to human legal professionals for final review. Documents can be further edited directly in Lexis+ AI or exported to Microsoft Word.
• Suggest legal workflow actions based on the type of documents uploaded (e.g., Draft a Legal Memo, Summarize, Draft an Argument) and dynamically generate follow-up prompts that are personalized to the lawyer’s workflow.
• Provide prompt assistance, proactively suggesting refinements to queries to help the user accomplish their goals efficiently.
• Allow users to securely upload and save tens of thousands of legal documents to Protégé Vault. On each Vault, users can perform numerous AI tasks to summarize, draft, research, and more.
• Draft deposition questions based on fact patterns, descriptions of witnesses, and other relevant information.

• Draft discovery documents, including Interrogatories, Request for Production of Documents, and Request for Admissions.

• Generate a graphical timeline of events from uploaded documents.
• Ask questions of or summarize large, complex documents of up to 1 million characters or approximately 300 pages—a 250% increase over previous processing limits.

• Enable users to upload transactional documents and conduct streamlined, systematic analyses with speed and accuracy.
• Review an uploaded motion or argument and find similar motions and arguments in the LexisNexis system to help the user refine their argument, find stronger authority, and identify potential weaknesses.
• Link quotes in litigation filings back to source documentation to confirm accuracy.
• And much more.

“LexisNexis is focused on improving outcomes and unlocking new levels of efficiency and value in legal work to support our customers’ success,” said Sean Fitzpatrick, CEO of LexisNexis North America, UK, and Ireland. “Our vision is for every legal professional to have a personalized AI assistant that makes their life better, and we’re delighted to deploy that through our world-class, fully integrated AI technology platform.”

Protégé can be personalized and grounded in a customer’s own documents and past work product via Document Management System (DMS) integration as well as the LexisNexis comprehensive repository of trusted legal content and metadata. This capability gives users:

• Customization control for better results and a more tailored AI experience, empowering them to share their role, practice area, jurisdiction, and style preferences to ensure the drafting style and output are highly personalized.
• Ability to query, extract clauses, and draft from their firm's knowledge base, streamlining access to necessary precedents. DMS integrations include iManage, NetDocuments, Sharepoint, and others.
