Last updated: October 22, 2026
What is Lexis+ with Protégé (formerly Lexis+ AI)?
Lexis+ with Protégé is LexisNexis Legal & Professional’s legal research and workflow platform for lawyers, legal departments, government, and law schools. It combines LexisNexis content with drafting, document analysis, citation checking, and general AI models. Pricing is customized by organization size, content, seats, and capabilities, with no public monthly entry price.
Lexis+ with Protégé is LexisNexis Legal & Professional’s legal AI workflow product, formerly called Lexis+ AI. LexisNexis says Lexis+ AI debuted in October 2023 as a generative legal research platform, followed by a second-generation release in April 2024. Protégé became generally available in the United States in January 2025, and the product was renamed Lexis+ with Protégé in February 2026. It serves law firms, corporate legal departments, government agencies, law schools, and individual legal professionals. Its central distinction is grounding responses in LexisNexis legal content, including Shepard’s citation data, while permitting approved use of a firm’s documents and work product. The product connects research with drafting, review, and matter-focused tasks.
A typical session starts with a conversational legal question, an uploaded pleading or contract, or a drafting request. The platform can search authoritative content, summarize a document, draft a motion or transaction document, suggest follow-up actions, and connect quotations to source material for checking. Protégé can recommend actions based on an uploaded file, generate timelines, draft deposition questions and discovery requests, and support Deep Research for complex issues. With explicit permission, it can draw on a document-management system and store large collections in Protégé Vault. Microsoft Word users can continue editing through Lexis Create+. Human review remains necessary, particularly for citations, facts, legal judgment, confidentiality, and final drafting decisions. Output quality also depends on the prompt, source material, and selected model.
LexisNexis describes Protégé as a personalized, agentic assistant using proprietary agentic and generative technology, rather than a single disclosed foundation model. Its legal configuration is grounded in LexisNexis sources and includes Shepard’s capabilities. Protégé General AI, commercially available from October 2025, offers model choice including Anthropic Claude Sonnet 4 and OpenAI GPT-5, GPT-4o, and o3. LexisNexis reported a 250 percent increase in document processing capacity in its January 2025 announcement, reaching up to one million characters or about 300 pages. Other 2025 releases added voice interaction, planning and self-reflection agents, AI analysis of search results, and expanded workflow assistance. Availability can depend on subscription configuration, jurisdiction, and customer permissions.
LexisNexis does not publish a standard monthly price for Lexis+ with Protégé. Its current product page says quotes vary with organization size, selected capabilities, and content access, so the public tier is Custom rather than a consumer free plan or fixed entry package. The broader Lexis+ product offers online-store options for one to three attorney firms and free-trial sign-up, but LexisNexis lists no free or fixed-price Protégé tier. A January 5, 2026 large-legal price schedule lists Lexis+ with Protégé generative AI drafting among subscription and transactional offerings, while also stating that list charges do not represent flat-rate subscription prices. Prospective buyers should request a quote and clarify seats, content, usage, integrations, document charges, renewal terms, and trial conditions.
The main tradeoff is authority and workflow integration against a less transparent buying process and the need for attorney verification. Lexis+ with Protégé competes most directly with Thomson Reuters CoCounsel Legal, vLex Vincent AI, and Harvey. CoCounsel Legal combines Westlaw and Practical Law content with research, analysis, and drafting. Vincent AI focuses on vLex content and multilingual legal work, while Harvey supports professional services workflows across research, drafting, and analysis. LexisNexis emphasizes model choice, Shepard’s checking, customer-controlled personalization, and encrypted handling, but it does not publish a simple self-serve price or a complete model-performance benchmark. Choose it when LexisNexis content, citation validation, document work, and firm controls matter more than transparent pricing.

Technical Details
Frequently Asked Questions
How much does Lexis+ with Protégé cost?
LexisNexis uses customized pricing. The quote depends on organization size, seats, selected capabilities, and the scope of LexisNexis content. The company does not publish a fixed monthly entry price for Lexis+ with Protégé. Small firms can review online Lexis+ packages, but those listings do not establish a free or fixed-price Protégé plan. Buyers should request written pricing for their specific configuration.
Does Lexis+ with Protégé have a free plan?
No free Protégé tier is publicly listed. LexisNexis mentions free-trial sign-up for Lexis+ and online purchasing for some one to three attorney firms, while Protégé pricing is handled through a customized quote. Buyers should confirm trial availability, included content, seat counts, usage terms, document charges, renewal conditions, and any restrictions before signing.
How does Lexis+ with Protégé compare with CoCounsel Legal?
Both products combine legal research, document analysis, and drafting with proprietary legal content. Lexis+ with Protégé centers on LexisNexis sources, Shepard’s citation capabilities, Protégé personalization, and selectable general models. CoCounsel Legal centers on Thomson Reuters content such as Westlaw and Practical Law. The better fit usually follows the research library, content rights, security requirements, and workflow integrations a firm already licenses.
Does Lexis+ with Protégé train AI models on customer data?
LexisNexis says customer data is not used to train public AI models or improve performance for other customers. It also describes encryption, user-controlled personalization, retention and deletion policies, and privacy governance. Organizations should still review the applicable contract, configuration, document-management permissions, retention settings, administrator controls, and regional data requirements before uploading confidential work.
Can firms use Lexis+ with Protégé for commercial legal work?
The product is sold to law firms, corporate legal departments, government agencies, and law schools, and its features target professional legal research, drafting, and analysis. Commercial use is therefore within its intended market, subject to the customer’s subscription and content rights. Users remain responsible for professional review, confidentiality controls, citations, and compliance with applicable client and court obligations.
