Vault and General AI: how Protégé helps you work faster and with confidence

Legal professionals are under constant pressure to deliver high‑quality work, manage growing volumes of information, and move quickly—without compromising accuracy or confidentiality. That’s why we continue to evolve Protégé on Lexis+ Hong Kong, with enhancements designed specifically for the realities of legal practice.

We’re pleased to introduce two major updates now available to Hong Kong users: Vault and General AI. Together, they provide a more connected, secure, and practical AI experience that supports your work from start to finish.

Vault: continuity, control, and cofidence

One of the biggest challenges legal professionals face when using AI tools is maintaining continuity. Work often involves multiple documents, repeated analysis, and ongoing refinement. Losing access to uploaded materials or needing to restart tasks disrupts productivity.

Vault solves this problem by providing a secure, persistent workspace within Protégé.

With Vault, you can upload documents once and return to them whenever you need, making it easier to manage large or complex matters.

Vault supports a wide range of legal tasks, including: Asking targeted legal questions across your documents Summarising long or complex materials Creating timelines from factual records Extracting key entities such as parties, dates, and locations Comparing multiple documents Drafting clauses or transactional documents based on your source materials By keeping your documents available throughout the lifecycle of your work, Vault helps reduce duplication, save time, and maintain focus.

General AI: supporting the work around the legal work

Legal matters rarely exist in isolation. Lawyers and legal professionals also need to research background information, prepare business materials, and communicate across languages.

General AI extends Protégé beyond legal‑specific workflows, giving you a secure space to handle general tasks alongside your legal analysis.

You can use General AI to:

• Research publicly available topics
• Gather real‑time information
• Draft non‑legal content such as presentations or summaries
• Translate materials accurately and efficiently

Toggle between Legal AI and General AI to complete more AI‑driven legal and non‑legal work in one secure Protégé environment—without switching tools.
Legal AI  Purpose‑built for authoritative legal work Get trusted, verifiable legal answers grounded in LexisNexis’ authoritative content.	General AI Support your day‑to‑day work - just a toggle away.   Switch to the General AI home screen to handle broader tasks alongside your legal work.

Because General AI is built into Protégé, you don’t need to move between tools or platforms. Everything happens in one place, under the same security and governance standards.

Private, secure, and authoritative by design

Trust is essential when adopting AI in a legal environment. Protégé is built with this principle at its core.

• Private: Customer data and prompts are not used to train public AI models.
• Secure: Enterprise‑grade security, controls, and governance help support responsible AI use.
• Authoritative: Outputs are grounded in LexisNexis’ trusted legal content and deep domain expertise.

This foundation allows you to use AI confidently, even when working with sensitive documents and complex legal issues.

Designed to fit how you work

Vault and General AI are not standalone features—they are part of an integrated experience designed to support legal professionals end to end. Whether you are analysing documents, drafting content, or managing supporting business tasks, Protégé helps you work more efficiently without compromising quality or security.

Vault has now been incorporated into all existing Protégé Hong Kong customer accounts, unless otherwise specified.
