Westlaw Edge features

Making once nearly impossible research tasks possible

Get access to AI-powered tools like intelligent document analysis, a powerful legal search engine, and integrated litigation analytics that can help you expedite legal research tasks that were once incredibly complex and time consuming.

How is Westlaw Edge different?

Built on Westlaw’s 100+ year editorial legacy and enhanced with AI technology to help you research in ways never before possible

Quick Check

This intelligent document analysis tool enables you to simply upload a brief – yours or your opponent’s – and in just minutes identifies any bad law and surfaces any additional highly relevant authority, as well as authority contrary to what your opponent cited.  

Use Quick Check to improve the quality and thoroughness of your work, without sacrificing time.

Litigation Analytics

Powered by the largest collection of federal and state dockets, Litigation Analytics compiles information on judges, courts, damages, attorneys, law firms, and case types to help you build the strongest case strategy across the most practice areas.

Use these insights to better set and manage client expectations related to likely timelines, outcomes, and cost of litigation. Also, know your opponent in terms of their experience, success record on motions, and how the legal organization fares for a motion in front of your judge. 

KeyCite Overruling Risk

As an evolution of KeyCite, Overruling Risk warns you when a point of law has been implicitly undermined based on its reliance on an overruled or otherwise invalid prior decision.

This citation safeguard reduces the possibility of being at risk for something you didn’t know existed. It uses artificial intelligence to uncover when a case may be stating the law in a way that has been invalidated, going beyond direct citing relationships.

WestSearch Plus

The most advanced legal search engine, powered by artificial intelligence and built on our proprietary editorial enhancements.

Simply enter your search terms, and WestSearch Plus will anticipate your search objectives to instantly provide answers to thousands of types of legal questions to get you to the heart of your matter faster.

This way you don't have to craft complex queries or spend time digging through search results to get to exactly what you are looking for. 

Statutes Compare & Regulations Compare

Streamline your legal research with the click of a button and instantly compare any two versions of a statute or regulation to see exactly what has changed over time.

Statutes Compare and Regulations Compare eliminates the need to manually compare legislative changes, and helps you better understand the intent of the changes to the law and whether the language has become more or less restrictive.

Coverage includes all statutory content and federal regulations with versions, plus state regulations in select states.

Jurisdictional Surveys

Speed up the creation of your survey by retrieving a customized and relevant compilation of laws across all U.S. jurisdictions on any topic.

Simply start with the citation of a statute you know, index terms that describe your topical target, or from a pre-defined topic page, and get a curated list of statutory sections that accounts for varying terminology across all jurisdictions.

Within minutes, you can assess laws across jurisdictions, understand jurisdictional variances as they relate to compliance activities, refine a legal argument, or identify new or emerging policy trends.
