LexisNexis has always emphasised two critical AI development tenets:
  • Users are in control of personalisation
  • Data they share is not used to inform performance for other users

Lexis+ with 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. Data shared is not used to inform performance for other users.

By putting the user in control and providing transparency around data access and personalisation settings, Lexis+ with 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.

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

LexisNexis maintains strict data privacy and governance standards across all AI development.
  • Customer data is not used to train public AI models
  • Customer data is not used to enhance AI performance for other customers
  • Personalisation features are controlled by the user
  • Personally identifiable information is protected in accordance with global data protection laws

LexisNexis has established privacy principles, governance structures, and compliance programmes to ensure data privacy requirements are met across all jurisdictions where we operate.

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 adds them to 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.
  • Results from Protégé Vault are retained for 90 days under “My Conversations” history.
