Why FillOnce
Built from forms you’ve already filled
Upload a filled PDF, Word document, or Excel sheet. FillOnce saves matching details under People, no long profile setup.
We can’t read your data
Details and documents are encrypted in your browser with your account password before they reach our storage. Once that one-time setup is done we can’t read them, and we never sell them.
You submit, never us
Matched fields fill in, then stop. You review everything and submit yourself. FillOnce never sends a form on your behalf.
Who it's for
FillOnce works for anyone with forms. Pick the version that sounds most like you. The product underneath is the same.
Families & parents
Camp, school, sports, medical — reuse each kid’s details on the next PDF or Word packet without retyping.
Job seekers
Job, college, and scholarship applications. Reuse what you already typed; you review before you submit.
Patients & caregivers
Intake forms, insurance, referrals, for you and family members you manage.
Renters & buyers
Rental apps and lease paperwork, save income and references once.
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 regular web form in Chrome, or a fillable PDF, Word, or Excel sheet under Forms. FillOnce matches fields to your saved details.
Fill, review, submit yourself
Matched fields fill in. You check the page and submit. FillOnce never submits for you.

Your details stay yours
Browser autofill often syncs answers to a vendor. Password managers mainly cover logins and cards. FillOnce helps with PDF, Word, Excel, CSV, and regular web forms from details you save under People. Once set up, they're encrypted in your browser so we can't read them. 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. Form field labels reach our servers so we can match them, and when you import a filled form the values it extracts pass through our API briefly for matching (never stored or logged). Your saved details stay encrypted with your key, so we can't read them. See our Privacy Policy for exactly how files are processed.
What forms does it work on?
Fillable PDFs, Word (.docx) forms with blanks, boxes or checkboxes, and Excel or CSV sheets that list a question next to each answer. Flat PDFs are beta; image uploads use browser OCR best-effort. We do not claim every document or every webpage.
Why not every form on the internet?
Autofill needs labels or widgets we can find. Most camp, school, rental, and intake PDFs/Word sheets have those. Closed custom widgets, cross-origin embeds, and handwritten-only scans often do not, so we detect what we can, show honest gaps, and never auto-submit.
How is my data protected?
Once your vault is set up, saved values and document files are encrypted in your browser with a key only you hold (AES-256-GCM), so we store ciphertext we can't read. Two exceptions, both disclosed on the security page: values extracted during import pass through our API briefly for matching, and Word → PDF conversion sends that document to our conversion service. Neither copy is kept.
Is FillOnce free?
Yes. Free is for just you, with unlimited saved details and 3 filled forms a month. Plus ($7.99 CAD/month or $69 CAD/year) adds up to 6 people in your household, unlimited filled forms, file conversions and locked (flat) PDFs, and stamping your saved signature.
