Case law search and AI legal research that finds the right case in plain English
Ask a legal question the way you would say it out loud. Cases returns the on-point precedents, each with a plain-English summary, the holding, and a citation you can check.
Informational research, not legal advice. Always verify the citation.

Why researchers switch
Ask in plain English, get on-point precedents, and check every citation
The incumbents cost hundreds a seat, run on boolean terms and connectors, and are sales-gated. Cases is transparent, plain-English, and built so you can verify every case you cite.
Search in plain English, not boolean
01Ask a legal question the way you would say it out loud. No terms and connectors, no boolean strings to build. Cases reads what you mean and returns the on-point precedents, so you spend your time reading cases instead of fighting a query syntax.
Get on-point precedents with summaries and holdings
02Each result comes back as a headnote card: a plain-English summary of what the case was about and the holding, so you see how the court ruled at a glance. You read the point that matters first, then open the ones worth a closer look.
Every citation is real and checkable
03The fear with legal AI is invented cases. A Stanford study found even paid legal AI tools hallucinate on a meaningful share of queries, and courts have sanctioned filings built on fake cites in Mata v. Avianca. Cases shows you the citation so you can confirm it in the official reporter. Informational research, not legal advice. Always verify the citation.
Find the right case in minutes, not hours
04One plain-English question surfaces the on-point cases with the summary and holding already on the card, so the hours normally lost to reading down a boolean result list become minutes. You still read and verify, you just start from the right place.
How it works
Ask in plain English, find the on-point cases, read the holding, verify the citation
Ask in plain English
Type your legal question the way you would say it to a colleague. No boolean, no terms and connectors. Describe the issue, the facts, or the rule you are trying to pin down, and Cases takes it from there.
Cases finds the on-point cases
Cases searches U.S. federal and state case law and returns the precedents that actually address your question, ranked by how on-point they are, as headnote cards rather than a raw boolean result list.
Read the headnote, holding, and citation
Each card gives you a plain-English summary of the case, the holding so you see how the court ruled, and the real citation. You read the point that matters first and decide which cases are worth opening in full.
Verify the citation in the official reporter
Cases shows you the citation so you can confirm it in the official reporter before you rely on it. This is informational research, not legal advice, and the attorney stays the gatekeeper. Always verify the citation.

Learn more READ - THE HOLDINGSummaries and holdings
A case is only useful once you know what it held. Cases returns each precedent as a headnote card with a plain-English summary and the holding, so you understand how the court ruled without reading the whole opinion first.
Learn more TRUST - REAL CITESVerifiable citations
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.
Learn more PRECEDENT - ON POINTFind precedent
Finding the case that is actually on point is the hard part. Cases does legal precedent search in plain English, surfaces the precedents that address your issue, and shows how courts ruled so you can see whether they help or hurt.

The trust problem, solved honestly
Every result is a real case with a citation you can check
The reason lawyers have been sanctioned for AI research is invented cases (see Mata v. Avianca). Cases shows you the citation for every result so you can confirm it in the official reporter. We do not claim to be perfect. We make verification trivial, because you stay the gatekeeper.
Meyer v. Uber Techs., Inc.
868 F.3d 66 (2d Cir. 2017)The court enforced an arbitration clause reached through a clickwrap sign-up, holding that a reasonably conspicuous notice of terms plus an unambiguous manifestation of assent binds the user.

FAQ
Legal research FAQ: the questions researchers ask first
No. Cases is an informational legal research tool, not a lawyer and not a substitute for one. Every result is a starting point you review and verify, and the attorney stays the gatekeeper. Use it to find and understand cases faster, then confirm anything you rely on.
Every result maps to a real, checkable citation, and we show you that citation so you can confirm it in the official reporter. We do not claim to be 100 percent hallucination-free, because no legal AI honestly can. What we do is make verification trivial: the citation is right there on the card, so you never have to take a case on faith.
Cases is transparent, self-serve monthly pricing that starts at 29 dollars per month, with no sales call, no quote, and no multi-year contract. Westlaw, Lexis, and Bloomberg typically run from 150 to 700 dollars or more per seat each month and are quote-only. You can start today and cancel anytime.
Cases covers U.S. federal and state case law. That includes U.S. Supreme Court, the federal circuits, and state appellate decisions. We state coverage honestly rather than implying it covers everything, so you always know what you are searching.
No. You ask in plain English, the way you would describe the issue to a colleague. There are no boolean operators to learn and no terms-and-connectors syntax to build. Cases reads the question and returns the on-point precedents.
Cases is built for solo and small-firm attorneys, paralegals, law students and clinics, in-house counsel, and self-represented (pro se) litigants. It is for anyone who needs to find and read the right case quickly without an enterprise research contract.
