Zero Witness Legal
What we cover

Private AI for legal mattersA workspace for one matter

Its own chats, its own documents, its own authorities. Nothing about a matter is stored on our hardware, and the model can run in this browser tab so that nothing about it leaves your machine at all.

What it does

Reads your case file on your own machine
A deposition, a contract, a set of interrogatories. The file is read in this tab, split into passages and indexed here. The original is never uploaded. A question reads only the few passages that match it.
Checks every case an answer cites
Each citation is resolved against our own copy of the published case law, on hardware we own, where we hold it. What comes back is the case name, the court and the date — so a citation that resolves under a name nobody used is caught, which is the commonest shape a fabrication takes.
Says what binds you
Set the court a matter is in and each authority is labelled binding or merely persuasive there. That is the ordinary rule applied mechanically: it is not a citator, it says nothing about whether a case is still good law, and no copy here will pretend otherwise.
Searches the law itself
Our own copies of the case law, the US Code, the Code of Federal Regulations, the Federal Register, the federal rules and court rules — not the web, and not a model's memory of it. Type plain words or use connectors (retaliat! /5 causation), and narrow by court, date, judge or case type. It finds text containing what you typed; it carries no treatment signal and no headnotes.
Transcribes a recording here
A hearing, a client call, a deposition. Whisper runs in this tab; the audio is never uploaded.
Checks a draft before you file it
Drop in a brief and its cases, statutes, rules and quotations are checked. You see the exact list of citation numbers before anything is sent — not the case names, not your argument, not a word of the text around them. It also suggests citation format fixes and builds a table of authorities, both in this tab.

What it can’t do

It cannot tell you a case is still good law. Whether a case supports what you wrote is a model’s judgement here, not a lookup, so it shows you the passages it read rather than asking to be believed. It keeps no record of your work that anyone here could produce, and none can be added — which is the row that disqualifies us for anyone under a retention duty. Our copy of the case law is a snapshot and its coverage is uneven, so a citation we cannot confirm is a reason to check rather than proof of a fabrication.

Every court and code we hold, and those we don’t.

Free, no account, and early. Checking the citations in a brief is the same machinery with nothing to set up.
