PolyglotFormFill reads a form in one language and fills it from your data in another — PDFs, Word, Excel, and web forms. On-device OCR turns a flat or scanned PDF into a real fillable form; an encrypted vault remembers your answers; translation and signing run locally. Nothing is uploaded — no account, no cloud, no tracking. A desktop app and browser extension share one vault. 7-day free trial, then a one-time purchase (no subscription).
