Move From Opinions to Final Outputs With US Case Law
Lawyers can produce sharper insights and drafts with US case law content at their fingertips in Harvey.
Lawyers spend 19% of their time researching case law. When legal research tools are fragmented, that time is spent on iterative manual search and context-switching rather than substantive analysis.
Harvey's US Case Law knowledge source gives lawyers direct access to millions of opinions, so high-quality research, analysis, and drafting happen in one place.
Find the right cases and start drafting faster
With the US Case Law knowledge source in Harvey, lawyers can quickly answer targeted inquiries and dissect hypotheticals. Harvey’s responses include direct citations to the source, so that lawyers can validate results and accuracy. Case content can be viewed directly alongside results, with no separate window or tool required – helping lawyers drill into the original material and ensure their analysis and recommendations are sound. Lawyers can use the US Case Law knowledge source to conduct early-stage analysis, and then turn to premium case content for high-stakes matters within the same platform.
Lawyers can also search across case law and their own uploaded files in a single prompt. For example, when preparing an initial defense strategy, a legal team can pull in relevant evidence and documents from a vault and analyze their own fact patterns against existing precedent. Additionally, a lawyer can draft sections of a memo by synthesizing case content with other relevant regulatory sources like the United States knowledge source, so that takeaways for the client are clear.

Edit documents in Word with direct case insights
Lawyers can pull in court opinion insights and ask questions directly in the Word Add-In, making it easier to reference relevant case law and pressure test arguments while drafting. This means that litigators drafting motions or briefs can still ensure results are grounded without interrupting their flow or switching tools.

Build repeatable research workflows for your team
Lawyers running high-volume work can embed the US Case Law knowledge source in custom agents through Agent Builder. For example, an in-house team can set up an employment investigations workflow and embed relevant state case law as a reference point for every run. Additionally, a law firm can create an agent to aid with trial prep by connecting witness testimony insights and inconsistencies to relevant legal doctrine, speeding up analysis and strengthening the resulting strategy. This allows lawyers to scale repeatable work across matters, while helping drive more consistent results.
Across research and drafting, the US Case Law knowledge source helps lawyers reference opinions, validate arguments, and quickly move towards drafts.
The US Case Law knowledge source includes over 9 million opinions from CourtListener. The US Case Law knowledge source is available starting June 3rd on a rolling basis to Harvey customers.
