Lexis+ AI is the generative AI product of LexisNexis for legal research, drafting and analysis. LexisNexis renamed it Lexis+ with Protégé in February 2026. It is a commercial tool for legal professionals, not a public search engine. Its answers use LexisNexis legal content, the customer's own documents and web sources. LexisNexis documents no crawler for it.
