Lexis+ with Protégé

Lexis+ with Protege is the flagship legal AI platform from LexisNexis, rebranded from Lexis+ AI in February 2026. Protege is the agentic AI assistant powering conversational research, document drafting, and analysis grounded in 161M+ verified legal documents with Shepard Citations validation. The May 2026 expansion introduced Protege Work (a skills and orchestration layer that creates structured plans for multi-step legal tasks), Protege Agentic Drafting (purpose-built drafting agents for contracts, motions, briefs, and deal documents), and Protege Workrooms (secure collaboration spaces shared among firms, clients, and counterparties). The platform includes 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 (reasons across uploaded firm documents). Customer base includes Am Law 50 firms, corporate legal departments, and law schools including Berkeley and Notre Dame. LexisNexis is part of RELX Group, a $70B+ publicly traded company. Lexis+ with Protege 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, allowing users to toggle between legal-tuned and general-purpose models. Protege Workrooms enable secure cross-firm collaboration with customer-held encryption keys (added May 2026). Voice-enabled interaction (launched March 2025) and dual-mode design (Protege Legal AI for authoritative workflows, Protege General AI for flexible tasks) extend the platform beyond text-only interfaces. No MCP server or public developer API is published. Pricing is custom with no public pricing page. LexisNexis offers trials ("Request a trial" on product page). Contact 1-888-AT-LEXIS or use the contact form. Pricing typically bundles with existing LexisNexis subscriptions, meaning standalone value depends on content licenses already held. Two separate Forrester Total Economic Impact studies (large law firms May 2025, corporate legal departments June 2025) quantify ROI for prospective buyers. Lexis+ with Protege is most useful for firms already in the LexisNexis ecosystem. Firms committed to Westlaw will find CoCounsel ($428/month bundled with Westlaw, 75 G2 reviews at 4.8) provides tighter integration with their existing Thomson Reuters research workflows. Harvey AI (custom pricing, $1.22B raised, $11B valuation) serves firms wanting legal AI independent of any single research database. For plaintiff-specific workflows, Eve (custom pricing, $163M raised) covers the full PI case lifecycle. Spellbook (from $99/month) focuses on contract review with a more accessible entry point. The Custom Workflow Builder is still maturing, and out-of-the-box workflows are currently stronger than custom-built ones. As of Q2 2026, the May 7, 2026 expansion launched Protege Work, Protege Agentic Drafting, Protege Workrooms, and customer-held encryption keys. Two Forrester TEI studies provide independent ROI validation for both law firms and corporate legal departments. G2 shows 2 reviews at 4.0 under the former "Lexis+ AI" name (the product was rebranded in February 2026, and reviews under the new name are expected to accumulate). The platform is grounded in 161M+ verified legal documents with Shepard Citations, the largest verified legal corpus. Customer data is never used to train AI models, with identifiable information removed from AI interactions. LexisNexis applies privacy by design principles at every stage of systems, products, and business processes.
