The problem
The same personal details get retyped into intake packets, applications and onboarding forms: PDF, Word, Excel and web.
What it automates
Filling the next form from details saved once in an encrypted vault, with every field shown for review before anything is submitted.
The result
Details are entered once instead of on every form, and the person stays in control of what gets filled and sent.
FillOnce reads a form the user has already completed, extracts the field mapping, and encrypts saved values with a key derived from the user’s passphrase, the service stores only ciphertext it cannot decrypt. On the next document it proposes matched values for review before anything is written, and the user submits the form themselves; FillOnce never submits on their behalf. Free tier, Pro at $9 CAD/month and a Family plan at $14.99 CAD/month for up to six household profiles.

Anyone dealing with repeat paperwork (intake packets, grant applications, compliance forms, onboarding documents) retypes the same details dozens of times. Existing autofill tools only handle web forms, and the sensitive data involved cannot sit in an unencrypted store.
