Secure General AI for Canadian Lawyers | Protégé™︎ General AI in Lexis+ AI™︎

Across Canada, lawyers are rapidly integrating artificial intelligence into their daily workflows, from early research to drafting memos, preparing client updates and exploring complex legal questions. Yet many professionals are still switching between specialized legal tools and general-purpose AI platforms such as ChatGPT or Claude to accomplish a full day’s work.

This fragmented approach creates two key problems:

1. Lost efficiency as lawyers jump between disconnected platforms.
2. Risk exposure, especially when confidential or privileged material is copied into external systems that may not meet a firm or company’s privacy, regulatory or client-mandated security standards.

Canadian firms have been seeking a way to use both legal-specific and general-purpose AI without moving sensitive information outside a trusted environment.

LexisNexis^® now delivers that capability.

Introducing Protégé^TM General AI — Now Available in Canada

LexisNexis Canada has launched Protégé General AI in Lexis+ AI^TM which allows users to select the large language model (LLM) that best suits the task at hand, all while staying within the secure LexisNexis ecosystem. This new capability was designed specifically for the diverse, fast-paced nature of Canadian legal practice, where lawyers often toggle between legal research, regulatory analysis, bilingual client communications, and non-legal work such as summarizing industry news or preparing presentations.

How Protégé Legal AI and Protégé General AI Work Together

Protégé Legal AI continues to serve as the authoritative, accuracy-focused option for:

• Canadian case law analysis
• Legal research across federal and provincial jurisdictions
• Drafting motions, memos, and agreements grounded in LexisNexis content
• Validating authorities with integrated LexisNexis Citations Service

When broader tasks arise, such as brainstorming arguments, generating bilingual summaries, or drafting communications for clients outside the legal field, users can now switch to Protégé General AI using a simple drop-down selector. Both modes operate under the same enterprise-grade security framework.
