Our Verdict

Lexis+ AI (with the Protégé assistant) is LexisNexis' AI-powered legal research platform. It combines the massive Lexis legal database with GPT-4-class AI to provide cited answers to legal questions, predictive litigation analytics, and automated document drafting. Unlike general-purpose AI tools, Lexis+ AI grounds every answer in verifiable case law and statutes — it shows you the citations so you can verify the AI's work. The platform is bundled with a Lexis subscription, which makes pricing enterprise-only and not publicly disclosed. Lexis+ AI is best for litigation teams and legal researchers who need deep case law analysis with verifiable sources, rather than contract review (which is better served by Spellbook or LegalOn).
