The fastest way to find what you need
First-of-their-kind tools offer the most efficient way to conduct research and find on-point cases
New capabilities deliver advanced speed and accuracy, providing you with greater confidence in your research.

Precision Research
Reveals important case attributes, enabling you to search, filter, and browse more efficiently than ever before. Run a search that gathers all the potentially relevant cases, then filter your results by legal issue, fact pattern, motion type, outcome, and more.

KeyCite Cited With
Find connections between cases that would traditionally be difficult to uncover. KeyCite Cited With allows you to quickly identify related cases that have a pattern of being cited together, even if neither cites the other.

Outline Builder
Quickly and easily build outlines without needing to leave Westlaw Precision. Open Outline Builder side by side with a document while researching, then drag and drop important text or citations directly into your outline.

KeyCite Overruled in Part
Identify the specific point of law in a case that has been invalidated so that other valid points of law aren’t missed. Look for a red-striped flag to indicate that a case has been overruled in part.

Keep List/Hide Details
Save potentially useful cases and hide cases you don’t want to inadvertently re-review. Selections persist across multiple searches to make your research even more efficient.

Graphical View of History
View a graphical visualization of your research history, mapping out the steps you took and the searches and documents you had more interaction with.
Tools such as intelligent document analysis, a powerful legal search engine, and integrated litigation analytics can help you expedite legal research tasks that were once incredibly complex and time consuming.

Quick Check
Improve the quality and thoroughness of your work without sacrificing time. Upload a brief to receive a report that surfaces any bad law, additional highly relevant authority, and authority contrary to what your opponent cited.

Litigation Analytics
View relevant data-driven insights on judges, courts, attorneys, law firms, damages, and case types so you can better manage client expectations and build the strongest case strategy.
