Caselaw Database With Real, Checkable Citations You Can Verify
The biggest fear with legal AI is invented cases. Cases is built the other way: every result maps to a real citation, shown on the card, so you can confirm it in the official reporter before you rely on it.
How courts have ruled
Sample results, illustrative only. Informational research, not legal advice. Verify every citation.
In short
A caselaw database is a searchable collection of court decisions you use to find and cite case law. Cases works as a plain-English front door to U.S. federal and state caselaw, and its defining feature is that every result carries a real, checkable citation. This matters because the number one buyer fear in legal AI is fabricated cases. A Stanford study found that even paid legal AI tools hallucinate on a meaningful share of queries, and courts have imposed sanctions when lawyers filed briefs built on fake cites, as in Mata v. Avianca. We do not claim to be 100 percent hallucination-free, because no legal AI honestly can. Instead we make verification trivial: the citation sits right on the headnote card, so you confirm the case in the official reporter yourself. Cases is informational research, not legal advice, and the attorney stays the gatekeeper on everything cited in a filing.
What you get
Verifiable citations, built for attorneys, paralegals, and law students
A citation on every result
Each case comes back with a real citation, so you are never handed a case name you cannot check.
Verify in the reporter
Copy the citation and confirm the case in the official reporter, exactly the check a court expects you to have done.
Honest about the risk
We do not claim to be hallucination-free. We cite the public Stanford study neutrally and design for verification instead of false confidence.
Built for the Mata problem
The sanctions in Mata v. Avianca followed fake cites that were never checked. Cases puts the citation in front of you so checking is the default.
