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.

Connect a model.

Use local Ollama, connect a provider directly, or use OpenRouter. Direct connections include Anthropic, Gemini, OpenAI, Fireworks, xAI, Groq, and Together AI. Provider keys are held in this computer's keychain and are never sent to us.

Open Settings → AI connection, add a connection, then choose Test and Refresh models. Ollama needs no key, but it must already be running with a model installed. Most hosted providers show a new key exactly once, so copy it before you close that tab.

Until a working model is connected NyayVaani can open matters, attach documents and hold briefs — but it cannot answer, review, or draft. If generation seems inert, check this connection first.

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. Text obtained from a scan is marked as OCR so you know to compare it with the page image. A file that cannot provide usable text is shown as needing attention 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.

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.
