Why FillOnce
Built from forms you’ve already filled
Upload a filled PDF, Word document, or Excel intake sheet. FillOnce saves matching details under People. No tedious profile setup.
We can't read your data
Your details and documents are stored encrypted with your key — we can't read them, sell them, or train on them. Matching never uses a third-party AI.
Never submits
Matched fields fill from your vault, then stop. You review and submit. FillOnce never sends a form on your behalf.

How it works
Save details from a form you’ve filled
Upload a filled PDF, Word, or Excel form (or type a few details). FillOnce saves them under People, encrypted so we can't read them.
Open the next blank form
A standards-based web form in Chrome, or a fillable PDF, Word, or Excel sheet under Forms. FillOnce matches fields to your saved details.
Fill, review, download
FillOnce fills every matched field from your vault. You review and submit yourself. FillOnce never submits for you.

The autofill that doesn't spy on you
Browser autofill ships your data to a third party. Password managers only do logins and cards. FillOnce fills standards-based forms, fillable PDFs, Word documents, and Excel intake sheets from a vault you control — stored encrypted with your key, so we can't read them — and matching runs without handing your data to an outside AI service (see how we protect data).
Frequently asked questions
Does FillOnce submit forms for me?
No. FillOnce fills the fields and stops, so you can review everything and submit yourself. It never auto-submits a form.
Do I have to type all my information in first?
No. In Forms, choose “I have a filled form to save from,” upload a fillable PDF, Word document, or Excel intake sheet you've already filled out, and FillOnce saves matching details under People. Then upload a blank form to autofill. Scanned image uploads are best-effort.
Is my data sent to AI?
No. Matching runs on our own systems, never a third-party AI. Your saved details are stored encrypted so we can't read them. See our Privacy Policy for exactly how files are processed.
What forms does it work on?
In the app: fillable PDFs (AcroForm), Word (.docx) with merge tokens, content controls, or labels with blanks, and Excel (.xlsx) or CSV label/value intake sheets. Flat PDFs are beta; image uploads use browser OCR best-effort. Standards-based HTML web forms use the Chrome extension (beta — sideload from Settings until the Web Store listing is live). We do not claim every document or every webpage.
How is my data protected?
Vault values and document files are encrypted in your browser with your key (BYOK) before they reach our storage, so we can't read them. Field labels may briefly reach our API for matching. See the security page for details.
Is FillOnce free?
Yes. Free includes 1 person profile, 5 stored documents, and 3 document exports per month. Web-form autofill uses the Chrome extension (beta — sideload until the Web Store listing is live). Pro adds unlimited documents and exports, supported file conversions, and e-signature. Family adds up to 6 household profiles.
