In a significant development announced on August 26, 2026, LexisNexis Legal & Professional introduced the next generation of Lexis+ with Protégé, marking the debut of the LexisNexis Legal Intelligence Engine. This dynamic AI-powered advancement transforms their previous agentic platform, enabling legal professionals to seamlessly transition from initial concepts to review-ready documents.
The hallmark of this release is the “harness” architecture, which innovatively orchestrates AI models, agents, skills, and content sources based on user-defined tasks, moving away from predefined workflows. This allows users to simply describe their objectives, guiding the system to generate output suitable for Microsoft Word, Excel, or PowerPoint, with enhanced adaptability and intelligence.
Jeff Reihl, executive vice president and chief technology officer at LexisNexis, highlighted the adaptive nature of the new platform: “It’s really creating an ecosystem bringing together all of our content, all of our capabilities, and the customer data, with a much more intelligent engine.” This facilitates integration across LexisNexis products, such as Lex Machina, Intelligize, and Law360, without requiring users to toggle between different tools.
A notable feature of the revamped Protégé is Shepard’s Verify, which extends citation verification into the drafting process by not only ensuring the accuracy of legal citations but also confirming their relevance to the task at hand, adding a layer of contextual intelligence.
The system’s capabilities also include enhanced memory, which remembers the context of a session, thereby improving workflow continuity. This memory feature allows the platform to recall previous similar cases and preferences, potentially introducing a personalized element to future platform iterations, as suggested by Reihl.
With a commitment to continuous improvement, LexisNexis plans to refine its AI models, leveraging past investments in reinforcement learning and exploring new models tailored to legal tasks. By enabling a more connected and efficient legal work environment, the LexisNexis Legal Intelligence Engine demonstrates a proactive approach to incorporating AI advancements into the legal profession’s everyday practices.
