Below are prominent legal databases that have rolled out generative AI tools. Currently, law school faculty and students have access to generative AI features within Lexis, Westlaw, Practical Law and Bloomberg Law.
Lexis+ AI is a conversational generative AI tool that Lexis launched in 2023, designed to assist with tasks such as answering legal questions, generating drafts, summarizing cases, and uploading documents for analysis.
Protégé is a personalized generative and agentic AI assistant within Lexis+ AI, introduced in a commercial preview in August 2024 and made available to law school faculty and students in early 2025. Protégé offers enhanced features, including the ability to draft full complaints, motions, and agreements. It also includes a "draft mode" for editing forms and documents directly within the AI interface. The updated upload function allows users to create interrogatories, deposition outlines, and timelines. Additionally, Protégé provides a secure "Vault" for users to upload and store documents for easy access.
In late March 2025, Lexis announced several new features for Protege, including voice-enabled chat and advanced agentic AI capabilities. These include a Planner Agent that breaks down complex legal questions into steps, an Interactive Agent that allows user modifications for tailored results, and a Self-Reflection Agent that refines its work for superior document drafting. These features will become available in the coming weeks.
Visit the Faculty Lexis+ AI page for additional information such as guidance for effective prompting and sample exercises. On-demand AI-related webinars, including recent demonstrations of Protégé's new enhancements, are available on the Faculty Training site (Lexis login required).
On November 15, 2023, Thomson Reuters announced a new AI offering called AI-Assisted Research within Westlaw Precision. This feature leverages Casetext's legal AI technology, CoCounsel, which Thomson Reuters acquired in August 2023. Law schools gained access to CoCounsel's features in January 2025. Westlaw Precision now includes a range of CoCounsel capabilities such as AI-Assisted Research, AI Jurisdictional Surveys, Claims Explorer, and more, enhancing legal research, litigation, transactional, and compliance tasks. Additional features will be coming soon to further expand its capabilities.
On-demand lessons and webinars are available on the GenAI Resources webpage (Westlaw login required).

Practical Law is accessible through Westlaw, and UC Davis Law affiliates can find the AI tool in the upper-right corner of the Practical Law screen after signing in. A brief training video and handout are also available.
Bloomberg Law is a legal platform that covers primary and secondary legal content, as well as chart builders and legal news for various practice areas, including litigation, corporate, and tax, to name a few. In recent years, Bloomberg has introduced AI-powered features, such as analytics for litigation and corporate deals.
