Lexis+ AI (now branded as Lexis+ with Protégé) is a generative AI legal research and drafting platform built on LexisNexis's legal content database. It's designed for attorneys and law firms, with AI-assisted features estimated at $50-125/user/month on top of base Lexis+ subscriptions, though some firms report receiving AI features bundled during contract renewals.
Lexis+ AI integrates generative AI capabilities into LexisNexis's legal research platform, powered by the Protégé AI assistant. The tool provides AI-assisted legal research, document drafting, case summarization, and analysis across case law, statutes, and legal content. It includes Shepard's citation validation and links AI-generated answers to authoritative sources. The platform is positioned for law firms seeking to compete with larger practices through AI-enhanced workflows, though independent reviews have raised concerns about accuracy—a Canadian law professor found content "riddled with mistakes," and Reddit users report it lags behind competitors like CoCounsel in capabilities.
No. Lexis+ AI requires a paid Lexis+ subscription as the base, with AI features adding an estimated $50-125 per user per month on top of that subscription. Some firms report receiving AI features bundled at no additional cost during multi-year contract renewals as LexisNexis competes for business. There is no free plan or free trial mentioned in available research.
Lexis+ AI integrates with Microsoft 365 through Lexis Create+ for AI-assisted legal drafting. It also connects with LexisNexis's own ecosystem including Practical Guidance, Lex Machina analytics, and CounselLink+ for corporate legal operations. Specific third-party integrations beyond Microsoft were not detailed in the research.
According to user reviews, Lexis+ AI lags behind competitors like CoCounsel (Thomson Reuters) in capabilities—Reddit users report it's "about a year behind." Alternatives like Paxton AI offer coverage of all 50 states plus federal law at potentially lower price points. However, Lexis+ AI's advantage is deep integration with the established LexisNexis legal content database and Shepard's citation system, which competitors may not match in breadth.
