Pritzker Legal Research Center: Generative AI Resources: WL / LX / BLaw AI Tools

Below are the generative AI tools offered to law schools by Westlaw, Lexis+ AI, and Bloomberg Law, as well as notes about upcoming features and tools not currently available to law schools that you may encounter elsewhere.

This page will be updated on an ongoing basis--the information below is current as of October 2024.

Westlaw

Ask Practical Law AI
Ask Practical Law AI allows you to ask legal questions in conversational language and uses large language models to focus on the text of Practical Law resources. These resources are referenced in the responses with the actual language from the resources, and links are included to read the full Practical Law documents.
CoCounsel Core (COMING SOON)
This tool will become available law school faculty on November 4, 2024, and to law students in January 2025.

CoCounsel Core supports the following 5 skills:
- Research: AI-assisted research using large language models that draw from Westlaw resources;
- Databases: Creating and searching databases on CoCounsel;
- Review: Review Documents and Compare Documents;
- Summarize: Summarize documents and Timeline;
- Draft: Draft and Prepare for a Deposition.

CoCounsel’s Research skill, in the early access program for law school faculty, is limited to using the “Search and Summarize Practical Law” generative AI tool. (CoCounsel’s Westlaw AI-Assisted Research skill will launch in January and will permit conversational language research queries. The Databases skill permits users to upload files to create and search custom databases. The Review skill allows users to upload files, review documents to answer specific questions, and compare documents, such as contracts. The Summarize skill allows users to request to have documents (like cases, legislation, or reports) summarized. This can also be used to provide a chronological timeline of events summarized from selected files. Lastly, the Draft skill can be used to draft documents, like correspondence or memoranda.

Lexis+ AI

Lexis+ AI Assistant
The AI Assistant supports 4 tasks:

(1) Ask a Legal Question: allows you to ask legal research questions in conversational language and generates answers using the following Lexis resources: case law; codes, rules, and constitutions; agency decisions; practical guidance, and treatises.

(2) Generate a Draft: supports 5 types of document: legal argument, legal memo, letter, email, and clause.

(3) Summarize a Case: generates a case summary including the procedural posture, overview, outcome, and citations.

(4) Upload and Summarize or Ask a Question: allows you to upload up to 10 documents and summarize them to create an overview of the facts, issues and legal reasoning of those specific documents.

A few things to note about Upload and Summarize or Ask a Question:
(a) This task is limited to answering questions from within the uploaded document(s). It cannot answer questions that require drawing from sources outside the document(s).
(b) Always be careful of uploading documents containing confidential information into AI tools. Documents uploaded for this task will be stored in the system for 10 minutes; your question history will be stored in the system for 90 days.

Another generative AI tool from Lexis that is not available to law schools or students, but that you may encounter in other employment settings, is LexisNexis Protégé. The main difference between the AI Assistant available to law schools and LexisNexis Protégé is the latter's personalization capabilities. There are currently no plans to offer LexisNexis Protégé to law schools.

Bloomberg Law

Draft Analyzer (with Clause Advisor)
Draft Analyzer allows you to upload draft agreements and uses AI to detect clauses and build a clause outline.
A semantic analysis engine then compares the language of a draft to publicly filed M&A agreements and identifies any text with a similar meaning.
Currently, Clause Advisor, the generative AI portion of this tool, is only available for M&A agreements. Clause Adviser assesses which side of a deal – buyer, seller, or neutral – an individual clause favors and allows a user to quickly modify the favorability of the clause. Plans to expand Cause Advisor to all types of agreements are currently underway.
Note: Always be careful of uploading confidential information into generative AI tools. Upon upload to Draft Analyzer, your draft is encrypted and secured for transmission. All text is wiped after processing and none of your information is saved in the system.
Brief Analyzer
Brief Analyzer allows you to upload a legal brief for analyses using AI tools. Brief Analyzer will identify and highlight the legal content of the brief, including key phrases, citations, and points of law, and then generate suggested content.
Note: Always be careful of uploaded confidential information into AI systems. Brief Analyzer allows you to decide before you start whether or not you want to save your analysis or automatically delete it when you log out.
Complaint Summaries
Complaint Summaries are an AI-generated explanation of the facts and allegations for most complaints that Bloomberg Law auto collects from the courts. The summaries appears for certain federal district court cases and the Delaware Court of Chancery. The Complaint Summary, if one is available, is visible directly on the docket sheet entry for the complaint.

The following generative AI tools are currently in development at Bloomberg Law:

(1) Bloomberg Law Answers Powered by Generative Al: When running a search, this feature will generate an answer or summary to the question or keyword utilizing Bloomberg Law resources. From the answer, you can access the documents used to generate the answer and see the exact section identified as most relevant.

(2) AI Assistant: AI chat assistant answers legal questions from case law, compares laws across multiple jurisdictions, summarizes and answers questions on opinions and statutes, and directs you to tools and topic pages across the site.
