What is the difference between Protégé and LexisNexis solutions?

Protégé is the AI assistant layer that powers and connects LexisNexis solutions. LexisNexis solutions—such as Lexis+ with Protégé, Lex Machina, CounselLink+, and others—deliver specific research, drafting, analytics, and matter management capabilities. Protégé enhances those solutions with advanced AI built on authoritative LexisNexis content and your organisation’s knowledge, helping teams work more efficiently while maintaining legal rigour.

LexisNexis Protégé™ is the legal AI assistant built on authoritative and exclusive LexisNexis sources.

What does AI personalisation mean in legal software?

AI personalisation adapts research results, drafting output, and analysis to match an individual users preferences, jurisdiction, practice area, and document history. Users control their personalisation settings and can modify or disable them at any time.

What is Protégé General AI?

What are extractive, generative, and agentic AI—and how are they used in Protégé?

Protégé combines three core types of artificial intelligence used in modern legal AI software: Extractive AI: Extractive AI retrieves specific information from existing legal documents and datasets. Used for precise legal research, document search, and targeted summarisation. Generative AI: Generative AI creates new content based on learned patterns. Used for legal drafting, conversational research, document summarisation, and timeline generation. Agentic AI: Agentic AI enables software to take action across multi-step processes. Used for guided legal workflows, proactive suggestions, and automated document analysis. By combining extractive, generative, and agentic AI, Protégé supports research accuracy, drafting efficiency, and structured legal workflows.

How much does Protégé cost?

Protégé is included within supported LexisNexis solution, Lexis+ with Protégé. It is not available as a standalone product.
