Lexis+ with Protégé review

Lexis+ with Protégé is the renamed Lexis+ AI; LexisNexis states the change took effect in February 2026 and that existing Lexis+ AI users now have access. The Protégé assistant runs research, drafting and analysis over LexisNexis primary law, exclusive secondary sources and Practical Guidance, which covers 25 practice areas. Its strongest feature for risk-averse firms is Shepard's Verify, which checks citations in AI answers, documents and drafts and flags unsupported statements. Vaults hold thousands of documents, spreadsheets, images and videos for analysis, Workrooms give teams shared spaces with permissions and activity history, and agent skills let a firm turn its templates and processes into reusable workflows. It connects to iManage, SharePoint and NetDocuments, and can pull in Lex Machina, Intelligize, CourtLink and Law360 content. LexisNexis says it never uses customer data to train AI models. Pricing is by quote, and the extra content sources depend on the options in your contract.
