Lexis+ with Protégé

Lexis+ with Protégé is the generative AI layer of the LexisNexis legal research platform. LexisNexis renamed the bundle from Lexis+ AI in early 2026. The Protégé assistant became generally available in the US in January 2025. It drafts transactional and litigation documents such as motions, briefs, and complaints. It answers research questions from LexisNexis case law, statutes, and Practical Guidance, and it summarizes documents and builds timelines. A Vault holds large sets of a firm's own documents for analysis. A Legal AI mode is grounded in Lexis content with Shepard's citation checks. A General AI mode runs OpenAI, Anthropic, and Google models inside the LexisNexis environment, with a Shepard's citation agent that checks legal sources in its answers. Integrations cover document management systems including iManage, NetDocuments, and SharePoint, and Microsoft Word through Create+. Its best fit is mid-size and large law firms, corporate legal teams, and law schools that already subscribe to Lexis. Pricing is quote-only and depends on firm size, capabilities, and content. Third-party estimates range from roughly 128 to 500 dollars or more per user per month, and Protégé is often quoted separately from the base Lexis+ subscription. The main limitations are the opaque, costly pricing and a long enterprise buying process. Reviews also say it is aimed at research rather than contract redlining, and that General AI mode does not apply Shepard's in the same way as Legal AI mode.
