What is LexisNexis Protégé?

LexisNexis Protégé is an artificial intelligence assistant that provides legal research, document drafting, professional analysis, and workflow automation capabilities across the LexisNexis product ecosystem. The platform combines generative AI, agentic task execution, and authoritative research content to support complex legal and business workflows. Protégé is integrated into Lexis+ with Protégé, Lexis Create+, Lex Machina, CourtLink, CounselLink+, and other specialized LexisNexis applications. Its legal research capabilities allow attorneys to investigate questions using primary law, statutes, regulations, secondary sources, and expert-authored Practical Guidance materials. Document drafting tools assist with preparing contracts, transactional agreements, litigation motions, legal briefs, complaints, and client correspondence. The assistant can analyze uploaded documents, summarize case materials, compare contractual provisions, and extract relevant facts from extensive document collections. Integration with Shepard's enables users to verify legal citations, review the treatment of authorities, and identify unsupported legal references. Protégé's agentic AI capabilities support complex multistep assignments, including legal research, document review, drafting, and structured analysis. Organizations can create and share reusable AI agent skills, collaborate through secure Workrooms, and store sensitive materials in document Vaults for ongoing analysis. The assistant integrates with Microsoft Word, Microsoft 365 Copilot, and document management systems such as iManage, SharePoint, and NetDocuments to connect AI workflows with existing organizational knowledge. Additional integrations extend Protégé into litigation analytics, court docket research, legal spend management, regulatory disclosure analysis, intellectual property research, and business intelligence applications.
