Lexis+ with Protégé

Lexis+ with Protégé is LexisNexis's flagship legal AI platform, replacing Lexis+ AI as of February 2026. Protégé is the agentic AI assistant powering conversational research, document drafting, and analysis grounded in LexisNexis's authoritative content library and Shepard's Citations. The platform launched with 300+ pre-built workflows covering motions, discovery, transactional documents, and contract redlining, plus a no-code Custom Workflow Builder for firm-specific playbooks. Three core agent types operate within the system: a Legal Research Agent (decomposes prompts and grounds answers in legal authorities), a Web Search Agent (open-web context), and a Customer Document Research Agent (analyses uploaded firm documents). Integrates with Microsoft 365 (Word, Excel, PowerPoint, OneNote, Teams, Outlook), iManage, SharePoint, OpenText, and Google Drive. LexisNexis partners with Anthropic, OpenAI, Microsoft, AWS, and Mistral for multi-model coverage; users can toggle between legal-tuned and general-purpose models. Customer base includes Am Law 50 firms, corporate legal departments, and law schools (Berkeley, Notre Dame). Pricing is custom. Call 1-888-AT-LEXIS or use the contact form. Customer data is never used to train AI models. Setup typically runs 2-4 weeks with vendor support. Best fit for firms already on the LexisNexis platform who want a unified AI workflow layer.
