  • Secure Collaboration: Protégé Workrooms enable shared, secure workspaces with clients and counterparties, plus customer-held encryption keys.

About Lexis+ AI

Introduction

Lexis+ AI has been rebranded and substantially expanded as "Lexis+ with Protégé," an end-to-end agentic workflow platform that LexisNexis launched in February 2026 to fully replace the original Lexis+ AI product. Built on LexisNexis's authoritative legal content and Shepard's Citations, Protégé now offers 300+ agentic workflows, and a May 2026 expansion added Protégé Work (multi-step task orchestration), Protégé Agentic Drafting (purpose-built drafting agents), Protégé Workrooms (secure shared collaboration spaces for firms, clients, and counterparties), and customer-held encryption keys for enhanced data control.

Legal Research

Legal research remains a core strength: conversational search lets users ask complex questions in natural language and receive citation-backed answers grounded in LexisNexis's database and validated via Shepard's Citations. Protégé personalizes results by jurisdiction and legal context, and Protégé Work now adds the ability to plan and execute multi-step research tasks autonomously rather than one query at a time.

Contract Analysis

Contract analysis uses the same AI and legal-database foundation to identify key clauses, flag risks, and suggest standard or improved language, with jurisdiction- and industry-specific tailoring. Protégé Workrooms now let internal and external stakeholders collaborate on contract review and negotiation within a shared, secure space.

Document Drafting

Document drafting was significantly upgraded in May 2026 with Protégé Agentic Drafting: purpose-built drafting agents for contracts, motions, briefs, and deal documents that go beyond clause suggestions to autonomously produce fuller first drafts anchored in LexisNexis content and firm context.

Legal Translation

Lexis+ with Protégé primarily supports English, with expanded bilingual support (English/French) for the Canadian legal market. It does not offer full conversational search or drafting in other languages, though users can search foreign-language terms using wildcard techniques on the underlying LexisNexis platforms.

Predictive Analytics

Predictive analytics is available through integration with Lex Machina, analyzing historical and current case data to forecast case trajectories, judge behavior, and litigation patterns. Nexis Data+ additionally provides access to over 36,000 licensed sources and roughly 45,000 total resources across 37+ languages for broader research and analytics needs.

Pricing

Lexis+ with Protégé sits on top of a base Lexis+ subscription and is quoted separately. Third-party trackers report the Protégé add-on running roughly $125-$275/user/month on top of an existing subscription, with the full bundled Lexis+ with Protégé plan ranging from about $128 to $494/user/month depending on scope, and full enterprise access to all agentic features reported at $500-$1,000+/user/month. Exact pricing requires a LexisNexis sales quote.

User Reviews and Ratings

Lexis+ with Protégé is generally well regarded for research accuracy and citation reliability, backed by LexisNexis's large team of technologists, data scientists, and legal experts. The main recurring criticism across reviews is premium, layered pricing that can be a barrier for solo practitioners and small firms.

Verdict

Lexis+ with Protégé is one of the most capable agentic legal AI platforms for firms already invested in the LexisNexis ecosystem, especially after the 2026 additions of agentic drafting and shared Workrooms. It is a premium, layered-pricing product best suited to firms and legal departments that can absorb the added Protégé cost on top of a base Lexis+ subscription.

Frequently Asked Questions

LexisNexis states it maintains established data privacy principles, governance structures, and control programs designed to protect personally identifiable information and meet privacy requirements across all jurisdictions where it operates; the May 2026 addition of customer-held encryption keys gives enterprise customers further control over their data.

Protégé is built with privacy and security controls to protect sensitive client data, including data isolation (one customer's data is not used to improve results for others) and, as of May 2026, customer-held encryption keys for enterprise customers. Users can control personalization settings and opt in or out of having their work product used for drafting or answering queries.

LexisNexis employs a large team of technologists, data scientists, and legal experts to develop, fine-tune, and validate Protégé's outputs. Answers are grounded in up-to-date, authoritative LexisNexis content with linked citations, and the 2026 Protégé expansion added agentic workflows with structured, auditable execution steps rather than single opaque answers.

The underlying legal database updates on a rolling basis: federal and key state court data typically refresh weekly (with some daily updates via Lex Machina), statutes and regulations update from daily to weekly depending on the source, and users can set custom alert frequencies for legal developments.

Lexis+ with Protégé primarily supports English, with expanded English/French bilingual support for the Canadian legal market. Full conversational search and agentic drafting in other languages are not yet offered, though LexisNexis platforms support foreign-language term searches using wildcard techniques.

Lexis+ with Protégé, launched in February 2026, fully replaces the original Lexis+ AI as LexisNexis's flagship platform. It expands well beyond conversational Q&A into an agentic workflow system, adding (as of a May 2026 update) Protégé Work for multi-step task orchestration, Protégé Agentic Drafting for autonomous document generation, and Protégé Workrooms for secure multi-party collaboration.
