Protégé General AI brings LexisNexis content, customer documents, and open web insights into one secure legal AI workflow
LexisNexis Legal & Professional announced the next generation of Protégé General AI inside the Lexis+ AI environment. It unifies authoritative LexisNexis legal content, your firm's documents, and open web insights-backed by Shepard's Citations-so you can move from question to draft to decision in one place.
Legal teams can choose between two modes: Protégé Legal AI for authoritative drafting and analysis, or Protégé General AI for broader work that blends legal, customer, and web sources. The result: fewer tool switches, clearer answers, and traceable citations.
What's new and why it matters
- Unified answers across sources: Combine LexisNexis content, your documents, and web insights in a single response. The system guides you to Legal AI when the task calls for authoritative legal workflows.
- Best Fit model selection-with control: A new default chooses the best model for each task. You can also manually select models like Claude Sonnet 4.5, Claude Sonnet 4, GPT-5.1, GPT-5, GPT-4o, and OpenAI o3.
- Trusted citations: Shepard's Citation Agent verifies recognized legal citations and links to sources so you can check the work fast.
- Flexible grounding: Choose any mix of LexisNexis content, open web, and your documents for context that fits the assignment.
- Advanced reasoning + Deep Research: Tackle high-complexity questions and toggle Deep Research when you need deeper analysis.
- Security and privacy by design: Fully encrypted within Lexis+ AI to support enterprise-grade data protection for general-purpose models.
- Streamlined workspace: Keep prompts, sources, citations, and drafts in one view for a cleaner, faster workflow.
How legal teams are using it
- Draft precise client emails, matter updates, and plain-language summaries for legal and non-legal audiences.
- Accelerate foundational research on technical topics and emerging areas like AI policy or crypto regulation.
- Strengthen recommendations with real-world context from non-legal sources where appropriate.
- Outline arguments, pressure-test counterpoints, and get a second opinion to refine strategy.
- Break down multi-layered issues across M&A, compliance, multi-party disputes, and new regulatory demands.
- Securely upload and analyze documents to generate summaries, issue lists, and versions for different audiences.
Under the hood: agentic infrastructure built for legal work
A new agentic architecture coordinates multiple AI agents to reason across diverse sources and steps. It extends Agentic Retrieval-Augmented Generation to better interpret intent, plan, and retrieve authoritative information so responses stay accurate and grounded.
- Orchestrator Agent: Coordinates tasks and agent handoffs.
- Legal Research Agent: Breaks down prompts into legal questions and answers with on-point authorities from LexisNexis content.
- Web Search Agent: Brings in relevant open web insights to add context where helpful.
- Customer Document Research Agent: Reasons over your documents and tools to deliver richer, context-aware analysis.
Security, governance, and model choice
Protégé runs within the encrypted Lexis+ AI environment with enterprise-grade privacy protections. LexisNexis builds and validates solutions in line with RELX Responsible AI Principles and supports a multi-cloud stack with partners including AWS, Anthropic, Microsoft, Mistral, and OpenAI.
You get performance, transparency, and authority-anchored by comprehensive legal content and validated through Shepard's Citation Service.
Why this matters for your practice
Legal work spans statutes, contracts, and the wider context that shapes outcomes. Protégé General AI respects that reality by blending sources, reasoning across them, and explaining the path it took-with citations you can trust.
As Sean Fitzpatrick, CEO of LexisNexis North America, UK, and Ireland, put it: legal professionals want one trusted legal AI workflow. This release aims to deliver exactly that.
