A PDF TOOL

Find the answer.
Check the source.

Open a PDF in your browser and ask about it. Every answer cites the passage it came from, and the citation takes you to that passage on the page. The free tier runs on your own hardware, which is what makes it free.

HOW IT WORKS

Three steps.
The PDF stays open.

You read the document while you ask about it. Nothing is hidden behind a chat window.

01

Bring your PDF.

Open a document in your browser. Domavel extracts its text and prepares it for questions.

02

Ask naturally.

Find a detail, clarify a passage, or ask where something is discussed. Answers stream as they’re generated.

03

Check the source.

Follow citation chips back to highlighted passages in the PDF. Keep your own judgment in the loop.

FEATURES

What's live
today.

The free tier reads one PDF on your device. Sign in for the hosted tier, which does more with a bigger model.

A bigger model, still showing its sources.

The hosted tier handles questions that need several passages joined together. Each part of the answer links back to the passage it came from.

WHERE THE WORK HAPPENS

Your machine
does the work.

There is no server bill behind the free tier, which is why there is nothing to charge for it.

Start on your device

It all happens in the tab.

On the free tier the browser does the parsing, the retrieval and the answering. The document’s text and your questions do not go to a backend, because on this tier there is no backend to send them to.

A small model, on your machine.

First use downloads it — about 2.2 GB, once. It is small enough to run on a laptop GPU, which means short, literal answers: good at finding a detail and showing you where it is, not at reasoning across a whole contract. You need a WebGPU-capable browser and enough memory.

Hosted picks up where it stops.

A bigger model on our servers, for the things a laptop GPU cannot do: multi-step answers, and filling in a form rather than only reading it. It needs sign-in, and extracted text and questions go to the backend and NVIDIA NIM. It is live now, and the free tier stays free.

PRICING

Free stays free.

The free tier runs on your own hardware, so there is nothing to meter and nothing to bill. It is not a trial and it does not expire.

Hosted runs on our servers. It is live now, and its pricing has not been set yet.

BEFORE YOU OPEN A PDF

A few good
questions.

Do I need an account?

Not for the free tier. The hosted tier needs an account: sign up with your email and verify it.

What browser and device do I need?

Use a WebGPU-capable browser, such as a supported version of Chrome or Edge, on compatible hardware. Model loading can take time and uses significant memory. Compatibility and performance vary by device.

Does anything get downloaded?

Yes. On first use the browser downloads the AI model — about 2.2 GB — and it is cached after that. Worth doing on wifi rather than mobile data. Local inference means processing runs on your device; it doesn’t mean the website never makes network requests.

What can the free tier actually do?

Ask about one open PDF and get a short answer with citations you can click back to. It handles “where does it say X” and “what is the figure for Y” well. It is weaker on questions that need several steps joined together, or that span more than the handful of passages it retrieves. Those are what the hosted tier is for.

Can I trust every answer?

AI can make mistakes. Check the cited passages and the original document, especially for important decisions. Citations help you verify an answer; they don’t guarantee it is correct.

What kinds of PDFs work best?

Start with PDFs that contain selectable text. Scanned image-only documents may not provide usable text; don’t assume OCR support.

Is the free tier really free?

Yes. It runs on your own machine, so there is nothing for us to bill — and no payment step to try it. The hosted tier is separate and its pricing has not been set yet. The free tier stays free.
