Which Legal Research Platform Is Right for You?

Which legal research tool is right for you?

Clio Work, Lexis and Westlaw are the top research tools for the legal industry. While they have some of the same capabilities, there are key differences between these platforms. 

Search capabilities and database breadth

Clio Work database and search capabilities

Clio Work enhances legal research by combining legal-specific AI with matter context, helping lawyers find and apply relevant information faster. Rather than relying on isolated searches, it connects research directly to the facts, documents, and history of a case.

Lawyers can ask natural language legal questions, use familiar search methods like Boolean searches, quickly surface relevant case law and concepts, and analyze uploaded documents to extract key issues, risks, and citations.

Because research happens within the matter workspace, insights are immediately actionable, making it easier to move from research to drafting, strategy, and client advice without switching tools.

Lexis database and search capabilities

Lexis provides a comprehensive legal database. This includes case law, statutes, verdicts, regulations, and legal documents filed with the courts. Lexis also offers secondary sources, guides, and access to news (both legal and non-legal).

A Lexis user can search by citation, browse a topic, enter a natural language query, or use Boolean logic. (Boolean logic uses words such as “and,” “or,” and “not” to narrow down or broaden searches.) 

Westlaw database and search

Westlaw also provides excellent coverage of case and statutory law across the U.S. For secondary sources, and offers thousands of practice guides and treatises. As for search options, Westlaw generally allows the same types of searches as the above. 

Advanced legal analytics & research tools

The key question in citation analysis is: is it good law? Clio Work, Lexis and Westlaw offer some unique tools that assist with citation analysis. The platforms also provide other advanced research tools, as outlined below.

Clio Work advanced tools

Clio Work brings advanced research and analysis capabilities directly into your matter workflow, using legal-specific AI to help lawyers move from insight to action faster.

Clio Work features the following advanced tools for research and analytics:

• Matter-aware AI analysis: Rather than analyzing documents in isolation, Clio Work reviews files within the full context of a matter—surfacing key facts, legal issues, and risks based on the entire case history.
• Document intelligence and summarization: Upload contracts, pleadings, or discovery documents and quickly extract key points, timelines, and relevant legal concepts without manual review.
• Natural language legal research: Ask questions like “What are the elements of negligence in California?” and receive clear, structured answers grounded in legal context, helping you get oriented faster.
• Contextual insights and recommendations: Clio Work connects research insights directly to your matter, helping identify next steps such as additional research areas, drafting opportunities, or strategic considerations.
• Integrated drafting and follow-through: Because research is embedded within the matter workspace, lawyers can immediately turn insights into action—whether drafting documents, preparing arguments, or communicating with clients—without switching tools.

Unlike standalone analytics tools, Clio Work focuses on making research usable in real time, reducing the gap between finding information and applying it in practice.

Lexis advanced tools

Lexis features the following advanced tools for research and analytics:

• Shepard’s Citation Service: This provides an updated view of how courts have treated a particular case or statute. 
• Brief Analysis: Lexis users can upload a brief or motion and initiate an AI-powered scan of the document with this feature. Brief Analysis will pinpoint the legal concepts from the document and provide recommendations for additional research.
• Lexis Answers: This provides answers to natural language questions, such as “What are the elements of breach of contract?”, which can be narrowed down to a particular jurisdiction.
• Search Term Maps: This tool maps your search terms within a case, empowering users to easily identify patterns and relationships.
• Ravel View: Ravel View is a graphic representation of top research results using circles and lines, with larger circles for the most-cited cases and lines displaying the citing relationships with other cases.
• Lexis+ Litigation Analytics: This tool provides insights into potential damages, judges, courts, and opposing counsel.

Westlaw advanced tools

Westlaw offers its own advanced features:

• Keycite: Keycite will answer the “is it good law?” question for a case, statute, regulation, or administrative decision. For intellectual property purposes, it will also confirm the validity—or lack thereof—of a trademark or patent.
• Claims Explorer: Enter the facts of your case and this tool will provide a list of potential legal claims to consider.
• AI Jurisdictional Surveys: Input a query on a legal question and receive an AI-generated starting point for research.
• Quick Check: When opposing counsel includes a quotation from a cited case, use generative AI to determine whether the quotation is used accurately.

Clio Work is offered as part of Clio’s case management platform, with pricing designed to give firms access to AI-powered legal research alongside practice management, billing, and client communication tools.
