◉ Polyglot · on-device · zero telemetry

Read & write any form —
in any language.

PolyglotFormFill reads a form in one language and fills it from your data in another — PDFs, Word, Excel, and web forms. Everything runs on your device; we never see your data. When you submit, it goes straight to the recipient you chose — never through us.

On your device — where all the processing happens

What leaves — only what you send, to whom you send it: a form you submit goes device → the recipient you picked, directly · a web search you type sends just those terms. Both are your choice, and neither passes through us. We never receive your documents, your vault, or any identifier — there is no cloud middleman.
The headline feature

Turn a non-fillable PDF into a form you can actually fill

A flat PDF with no form fields — or even a photo or scan of one — becomes a real, fillable form in seconds. No “print, hand-write, re-scan.” No uploading it to some website to do it.

🧩
Non-fillable → fillable

Any flat PDF, scan, or photo becomes an editable form

Point it at a PDF that has no fillable boxes, or even a picture of a paper form. On-device OCR reads the layout, finds where every field belongs, places real form fields there, and fills them from your vault — all on your machine, nothing uploaded. Then export a clean, filled PDF.

🔒

On-device, always

OCR, translation, filling and signing run locally. Your data never travels to us or anyone.

🌍

Polyglot fill

Fill an English form from your data in another language. Translation happens on your device.

📄

Word & Excel too

Fills .docx and .xlsx forms — named fields or flat labels — and can export a PDF.

🧠

A vault that learns

Answer a new field once; it's remembered — encrypted, on your device — for next time.

✍️

Trustworthy signing

Non-delegable, device-bound signatures with verifiable provenance. Nobody signs on your behalf.

🔑

Passkey-locked vault

Unlock with a passphrase or a hardware passkey (WebAuthn). The key is never stored — not even by us.

🔗

Desktop + browser

The extension fills web forms; the desktop app holds your keys as a hardened trust anchor.

Built for a multilingual world

Your data in your language. The form in theirs.

Governments and institutions publish forms in one language; people hold their details in another. PolyglotFormFill bridges that gap on-device — starting with English ↔ Hindi, with more to come.

Privacy

The promise, in one line

Your data is processed on your device and is never sent to us. The only things that leave are actions you take — submitting a finished form (straight to its recipient) or a web search you type. Those go directly to their destination, never through us. That's the whole list.
