LexisNexis has launched the next generation of Protégé General AI, unifying legal content, client documents, and web insights in a single, secure Lexis+ AI environment.
LexisNexis Legal & Professional has launched the next generation of Protégé General AI, expanding its Lexis+ AI platform to unify authoritative LexisNexis content, customer documents, and open web insights in a single, secure environment.
Protégé General AI is now commercially available in Canada following the successful launch in the U.S. and Australia.
Positioned alongside Protégé Legal AI, which is optimized for legal drafting and analysis, the updated Protégé General AI allows users to tackle a wider range of tasks—spanning ideation, complex problem-solving, and cross-domain research—while remaining grounded in trusted sources backed by Shepard’s Citations.
A new “Best Fit” mode can automatically select the most appropriate model for each task, while still giving users manual control. Legal professionals can choose from leading models including Claude Sonnet 4.5, GPT-5.1, Claude Sonnet 4, GPT-4o, GPT-5, and OpenAI o3. Responses can be grounded in any combination of LexisNexis content, web sources, and customer documents, with Shepard’s verifying and linking recognized citations.
LexisNexis says the upgraded Protégé General AI now delivers:
- Unified answers across sources, combining open web, LexisNexis content, and client documents in a single workflow.
- Advanced reasoning and Deep Research, allowing users to toggle deeper analysis for high-complexity matters.
- Security and Privacy by Design, with fully encrypted, enterprise-grade protections inside Lexis+ AI.
- A streamlined interface that keeps questions, sources, citations, and drafts together.
“Legal professionals want one trusted legal AI workflow solution,” said Sean Fitzpatrick, CEO, LexisNexis North America, UK, and Ireland. “Only LexisNexis can bring together agentic intelligence, customer documents, open web insights, and our authoritative content to produce next-level legal drafts and work output backed by Shepard’s.”
The release follows the October commercial launch of Protégé General AI and reflects what LexisNexis describes as a rapid cycle of customer-driven innovation. The platform now supports use cases including:
- Drafting client communications and plain-language explanations
- Accelerating foundational research in emerging areas like AI policy and crypto regulation
- Enriching legal strategy with real-world, non-legal context
- Testing arguments and counterpoints for complex disputes and transactions
- Securely uploading and analyzing documents across varied formats
Underpinning the upgrade is a new agentic infrastructure, with cooperating AI agents including an Orchestrator Agent, a Legal Research Agent, a Web Search Agent, and a Customer Document Research Agent. Together, they extend the capabilities of agentic Retrieval-Augmented Generation (RAG) to better understand user intent, plan multi-step work, and retrieve the most relevant authorities.
LexisNexis positions Protégé General AI as the next step in trusted, private, and authoritative legal AI workflows, aimed at helping legal teams move faster while maintaining confidence in the accuracy and provenance of their answers.
