Initial take, not yet hands-on testedLexis+ with Protégé
Our verdict
Lexis+ with Protégé (it was called Lexis+ AI until February 2026) is the Lexis answer to CoCounsel: drafting, research, and citation checking built on LexisNexis content. It makes the most sense for current Lexis subscribers. Pricing is quote-only.
Best for: Lexis subscribers who want AI inside the research platform they already use.
Watch out for: Value depends heavily on your existing LexisNexis subscription tier.
