Westlaw Edge saves at least a few minutes for each search that you’re doing, which certainly adds up. Even just saving 5-10 minutes per research assignment can add up to an hour a day.

Unrivaled research capabilities

Westlaw Edge includes access to powerful tools designed to help you complete research tasks in less time without sacrificing accuracy.

Analyze briefs with Quick Check

Quickly complete a comprehensive review of your brief – or your opponent’s. Quick Check securely analyzes briefs to suggest highly relevant authority that traditional research may have missed. Use it to check your own work, identify potential weaknesses in your opponent’s document, or compare multiple filings from a matter.

Review data and opponent information with Litigation Analytics

Develop a stronger litigation strategy and better manage client expectations in terms of cost, timing, and likely outcome. Informed by data points mined from litigation documents, Litigation Analytics can give you insight on your judge’s ruling tendencies, your opponent’s experience on a particular issue, and more.

Identify implicit risks with KeyCite Overruling Risk

Traditional citators identify when a case has been explicitly invalidated by a subsequent ruling. However, they don’t warn when similar cases may have also been implicitly overruled or abrogated by subsequent new developments in the law. KeyCite Overruling Risk marks cases that have no direct citations pointing to their invalidity.

Save time with Statutes Compare and Regulations Compare

Save time manually comparing legislative changes with Statutes Compare and Regulations Compare. With the click of a button, you can instantly compare any two versions of a statute or regulation and see exactly what has changed.

AI powered search with WestSearch Plus

WestSearch Plus utilizes advanced artificial intelligence to surface the information you need right to the top of your results. Save time digging through results lists and complete your research with confidence using the next generation of legal search.
