Lexis+ AI Legal Research Platform & AI Assistant

Lexis+ AI is a fully integrated, AI-enabled solution grounded in the largest repository of authoritative and exclusive legal content. It combines the power of AI with proprietary search technology to help legal professionals produce next-level work product and make informed decisions faster.

Protégé is the personalised generative and agentic AI assistant within Lexis+ AI that powers conversational search, insightful summarisation, intelligent legal drafting, and document upload and analysis capabilities. It’s tailored to each user’s preferences and can leverage both LexisNexis content and the user’s own documents. All Lexis+ AI users will now benefit from seamless access to the Protégé personalised AI assistant as a powerful new feature.

We regionalise hosting of our customers' Lexis+ AI documents, conversations and prompts to ensure they are stored in the Australia region.

Protégé is designed with robust privacy and security measures in place to protect sensitive client information and ensure compliance with relevant data protection regulations. Users can review and manage their personalisation settings at any time, allowing them to adjust the level of personalisation or opt out entirely if desired. Furthermore, the data they share is not used to inform performance for other users. By putting the user in control and providing transparency around data access and personalisation settings, Protégé aims to strike a balance between leveraging the power of AI personalisation to enhance legal services and maintaining the highest standards of privacy, security, and user autonomy.

LexisNexis has always emphasised two critical AI development tenets: users are in control of personalisation, and data they share is not used to inform performance for other users. With Protégé, customers decide which personalisation services are enabled and whether personal work product is used to answer questions or draft documents. LexisNexis remains committed to providing the most secure and confidential AI experience for lawyers and with new capabilities to unlock a more personalised AI experience.​



Finally, LexisNexis has a comprehensive data protection program to safeguard customer information, including encryption, compliance with data protection laws, and regular security assessments and audits.

LexisNexis is considered a leader in data privacy best practices and has established data privacy principles, governance structures and control programs designed to ensure that data privacy requirements are met, personally identifiable information is protected, and individuals’ privacy concerns are addressed across all jurisdictions where we operate.


Lexis+ AI uses private models, and no third party has access to it. User sessions are also secure, meaning that the input from one Lexis+ AI user does not bleed into the output of another (to preserve client confidentiality). Our models are hosted in protected accounts in commercial-grade cloud infrastructure, so we can manage performance and security.

Users can upload a collection of securely saved documents to a personal repository called a Vault. Protégé uses the documents stored in your Vault as the source for AI-powered tasks such as generating timelines, finding citations, analysing counterarguments, or drafting documents. Protégé will also suggest tasks based on the documents uploaded to the Vault, further guiding your work.​


• Create up to 50 Vaults with 1-500 documents per Vault. All data is securely stored and encrypted.​
• Uploading 11 or more documents automatically prompts you to create a Vault. Vaults are retained until you decide to delete them, and you can add/remove documents from your Vault at any time.​
• Uploads up to 10 documents, not saved to a Vault, are automatically purged at the end of each session.​
• Responses from Protégé Vault are retained for 90 days under "My Conversations" history.
