From installed to a cited answer.

Download and open it.

Get the installer for Windows or Linux. It is not yet code-signed, so Windows will report an unidentified developer — choose More info, then Run anyway.

There is no account, no sign-in and no server to reach. The app opens straight into your own workspace.

Bring your own model key.

The language model is the only part of NyayVaani that cannot run on a laptop. You bring a key from a provider you choose and pay directly — Anthropic, OpenAI, Google or Fireworks. It is held in this computer's keychain and is never sent to us.

Settings → Model access, paste the key, save. Most providers show a new key exactly once, so copy it before you close that tab.

Until a key is added NyayVaani can open matters, attach documents and hold briefs — but it cannot answer, draft or extract. If the app seems inert, this is almost always why.

Open a matter and point it at a folder.

A matter is a deal or a dispute: a name, a folder on this machine, and everything NyayVaani is allowed to read for it. Attaching a document does not copy it — the file stays where your firm's filing already puts it, and NyayVaani reads it in place.

PDFs and DOCX files are read for text and anchored by page and clause. A scan with no text layer attaches and is viewable, and is honestly excluded from search and citation checks rather than silently treated as empty.

Ask something you already know the answer to.

Start with a question you can check — an indemnity cap, a governing-law clause, a notice period. Every sentence that makes a claim about your documents carries a citation you can click through to the clause it came from.

That is the whole proposition, and the only way to judge it is against a document you know. A confident answer with no source is the failure mode this product exists to refuse.

Where beta actually shows.

Scans are not read

A PDF with no text layer is attached and shown, but not searched or cited. Reading them is coming; pretending to read them is not.

The AI cannot use tools yet

It answers from the documents in scope. It cannot go and fetch, search or act on its own — including through a connector you have added, which can be registered and tested but not yet used in an answer.

Citations are checked against your documents

Not yet against reported law. A quote is verified to appear in the file it claims to come from; whether the judgment it cites exists is a later release.

Windows and Linux

macOS will arrive signed rather than as an unverified first impression.

Something wrong, or something missing? Tell us what broke — a wrong answer with the document that produced it is the most useful thing you can send.
