Find real court opinions, cited
Ask about a case by name or topic and Zeplik searches a live legal database, then answers with the real opinion, its citation, court, and date. This matters because a language model on its own is notorious for inventing case citations that look authoritative and do not exist, a mistake that has sanctioned real lawyers. Here the answer is grounded in what the database actually holds, and when it cannot find or confirm a case it says so plainly rather than manufacturing one.
The lookup is free; you pay only the normal cost of the answer, shown before you send.
How it works
Name the case or describe the issue
Ask in plain language, like 'find the opinion in Brown v. Board of Education' or 'cases on qualified immunity for police searches'. A case name, party, or legal issue is enough for Zeplik to run the search.
Zeplik searches the live database
It queries a live public case-law database, not the model's memory, and treats each result as source material. The record is handled as untrusted content, so nothing inside an opinion can hijack the answer.
Read the grounded citation and verify
The answer returns the real case with its citation, court, and date, so you can click through and confirm at the source before relying on it, and ask follow-ups in the same conversation.
Worked examples
Real prompts you can open in the composer with the text ready to review. Nothing sends on its own. Swap in your own details.
Prompt: Find the Supreme Court opinion in Miranda v. Arizona and give me the citation
Zeplik looks the case up in the live database and returns the real citation, court, and date, so you cite the actual opinion instead of a confident guess.
Open this in ZeplikPrompt: Are there notable appellate cases about the fair use defense in copyright?
It grounds a topic search in real opinions from the database, each with its citation, rather than assembling a plausible-sounding list from memory.
Open this in ZeplikPrompt: I saw a citation for a case called Smith v. Jones, 123 F.3d 456. Can you verify it exists?
Verification is the point: it checks whether the citation resolves to a real opinion and tells you plainly if it cannot be confirmed, which is exactly how fabricated cites get caught.
Open this in ZeplikWhat it can and cannot do
The lookup is precise about what it can verify and honest about its edges. Here is the plain posture.
Search by case name, party, or legal issue and get real opinions from a live public case-law database.
Each result comes back with its actual citation, the deciding court, and the date, so you can locate and confirm it at the source.
Paste a citation and Zeplik checks whether it resolves to a real opinion, which is the direct antidote to hallucinated case cites.
If a case or citation cannot be found, Zeplik says so plainly instead of inventing an authoritative-looking opinion that does not exist.
It finds and cites cases; it is not your lawyer. Use it to locate and verify authority, then have a licensed attorney apply it to your facts.
Coverage reflects what the public database holds, which is broad but not exhaustive. A clean miss means the database returned nothing, not that no such case exists anywhere.
Grounded, and honest by default
- It cites real opinions. Every case comes back with its actual citation, court, and date, so you can verify each one at the source instead of trusting the model's memory.
- It will not invent a case. When an opinion or citation cannot be found or confirmed, Zeplik says so rather than fabricating a plausible-looking cite, the failure that has sanctioned real filings.
- Opinion text cannot hijack the answer. Each database record is treated as untrusted content: Zeplik reads and reports it but never obeys instructions embedded inside it.
Frequently asked questions
- Why not just ask a chatbot for a case citation?
- Because a language model on its own will confidently produce citations that look real and do not exist, a failure that has led to court sanctions against lawyers who relied on them. This tool searches a live case-law database and returns real citations you can verify, and it refuses to invent one when it cannot confirm a case.
- Which database does it search?
- It queries a live, free, public case-law database of court opinions. Give a case name, a party, or a legal issue and Zeplik returns the matching opinions with their real citations, courts, and dates.
- Can it verify a citation I already have?
- Yes, and that is one of its most useful jobs. Paste a citation and Zeplik checks whether it resolves to a real opinion, so you can catch a fabricated or garbled cite before it reaches a brief or a filing.
- Is this legal advice?
- No. It finds and cites real cases so you can locate and confirm authority, but it does not apply the law to your specific situation. For that, consult a licensed attorney. Zeplik is clear about this boundary.
- Does the search cost credits?
- The case-law lookup itself is free. You pay only the normal model-token cost of the answer written around it, shown before you send, like any other message.
