LexisNexis Releases Next‑Gen Protégé General AI With Unified Grounding and Agentic Workflow

The upgrade targets a secure, integrated workflow for enterprise legal teams wary of consumer AI tools.

Overview

  • The new release lets users combine LexisNexis legal content, open web results, and their own documents, with flexible source selection to ground outputs.
  • A Best Fit mode automatically picks the optimal model for each task, while users can manually select options such as OpenAI GPT-5.1 and Anthropic Claude Sonnet 4.5.
  • A new agentic infrastructure coordinates specialized agents — Orchestrator, Legal Research, Web Search, and Customer Document Research — to plan multi-step workflows across sources.
  • Legal citations generated by the system are checked and linked through Shepard’s via a dedicated Citation Agent for verifiability.
  • All features run inside the encrypted Lexis+ AI environment with enterprise privacy controls, including org-level disablement and user toggles for general AI access.
