LexisNexis launches Protégé™ in France, the next-generation, personalized legal AI assistant transforming legal practice

November 13, 2025

PARIS - LexisNexis, the global leader in legal information and analytics solutions, is launching Protégé™, its new artificial intelligence assistant designed to support legal and accounting professionals. An AI assistant that knows the law, understands legal practitioners, and fits seamlessly into their day-to-day work.

Following the launch of Lexis+ AI in early 2024, this announcement marks another major milestone for LexisNexis, which continues to enrich its ecosystem of technology solutions. Protégé embodies the new generation of AI assistants: reliable, integrated, and secure built to strengthen the rigor and efficiency of legal and compliance professionals.

A more expert, more contextual AI closer to how professionals work

Protégé™ is capable of understanding the context of a legal question, analyzing documents, drafting notes, clauses, or summaries, and formulating reasoned proposals backed by trustworthy legal references drawn from the LexisNexis corpus. 

Seamless integration across the LexisNexis ecosystem

Integrated across our solutions, it puts artificial intelligence at the heart of the professional experiencein the service of reasoning, precision, and time saved. Fully integrated with Lexis+ AI, Lexis Poly, Jarvis Legal, and Closd, Protégé™ extends the LexisNexis solutions already adopted by legal professionals. “This interoperability makes it possible to automate research, drafting, document synthesis, and audit preparation—while maintaining LexisNexis’s stringent security and confidentiality standards,” explains Jean-Pierre Sirot, Product Director, LexisNexis France.

Protégé™ within the LexisNexis ecosystem means:

Lexis+ AI

  • Delivers fast, well-reasoned answers with verifiable references from the LexisNexis corpus.
  • Lets you deepen, rephrase, or simplify as needed.
  • Adapts to the user profile (law firm lawyer, in-house counsel, notary, etc.).

Lexis Poly

  • Answers your legal questions with reliable sources from the LexisNexis corpus.
  • Automatically creates a complete corporate law file (from a Kbis extract, the RNE, or a key document).
  • Generates and enriches person sheets or matter files in seconds.
  • Summarizes and queries documents to extract the essentials.

Jarvis Legal

  • Answers your legal questions with reliable sources from the LexisNexis corpus.
  • Automatically organizes client matters and their documents.
  • Summarizes, compares, and translates documents instantly.
  • Assists with drafting instruments and letters; answers legal questions with reliable sources.

Closd

  • Automatically summarizes documents stored in data rooms.
  • Redacts sensitive information (planned for early 2026).
  • Will answer legal questions with reliable sources (planned for early 2026).

In short: Protégé™ saves time, secures answers, and integrates with the tools legal professionals already use. Unlike general-purpose AI, Protégé is designed from the ground up for the legal and regulated world: it combines the editorial reliability of the LexisNexis corpus, the security of a private environment, and seamless integration with existing practice tools.

A responsible, secure approach to artificial intelligence

Developed responsibly with human oversight, Protégé’s AI capabilities enable it to perform multi-step tasks, review its own results, and suggest improvements, freeing legal professionals to focus on strategic work. LexisNexis seamlessly incorporates each wave of AI innovation: research and analytics AI, which identifies relevant results and delivers insights; and generative AI, which produces content based on user prompts, grounded in LexisNexis’s proprietary, reliable data. The first building blocks of agentic AI—AI capable of carrying out multiple tasks autonomously under human supervision—are already part of the Protégé™ roadmap.

Innovation serving performance and security

With Protégé, LexisNexis strengthens its role as a strategic partner to legal and accounting professionals. The AI assistant enables them to combine speed, reliability, and compliance—drawing on LexisNexis’s recognized editorial expertise and exclusive content. And this is only the beginning, with a continuous stream of new features set to enhance the experience and use cases in the months ahead: control Protégé™ by voice, create a personal digital vault, and ask non-legal questions.

“Protégé™ reflects our vision of trustworthy, expert, and secure AI—capable of supporting our clients’ decisions and multiplying their added value. It is a key milestone in the digital transformation of the legal sector. Every legal professional should now be able to rely on a personalized AI assistant, and we are delighted to offer it in France through our fully integrated AI technology ecosystem,” says Éric Bonnet-Maes, CEO, LexisNexis France, and EO of LexisNexis CEMEA.
