fyllyoFILL ANY PDF
Automate filling
any fillable PDF form.
Your forms, not just ours. Add a blank fillable PDF. Fyllyo learns how to fill it, tests itself on test clients before you use it, then fills it from your documents on your Mac, as often as you need.
How it works
Follow the client-intake tutorial with downloadable test client documents →
Only have a flat or scanned form? Make the PDF fillable first, for free.
- 01Add the blank form
Choose a blank fillable PDF, one with fields you can type into. It can be any form you use, even an internal, regional or government form no software has heard of.
- 02Add instructions, if you have them
Official instructions are recommended. Fyllyo uses them to define each line and its conditions. A note of up to 4,000 characters is optional. You don’t map fields or write rules.
- 03Fyllyo learns the form
In Fyllyo Cloud, a large AI reads each page and records what every field means, whose value it is, the format the form asks for and when it applies. Then it writes the form’s calculations and one rule per field.
- 04Fill it with each new set of documents
Once it’s tested, the form fills on your Mac like a ready-made one, and every answer links to its source. Set it up once and reuse it every time.
It tests itself before you use it
Setup invents test clients with realistic documents, including traps such as masked SSNs, employer addresses and last year’s figures. It fills the form for those clients with the same local AI your Mac runs, works out why each miss happened, fixes the form’s program and tries again. The app shows the result. The form is ready to use early and keeps improving in the background.
Setup won’t make up rules. A format check must quote the sentence on the form or its instructions that states it, and conditions that could never apply are rejected.
Check it page by page
After setup, review the form page by page. Each field sits beside the blank page, marked “From the documents”, “Worked out” or “Left for you”.
When you fill it, Fyllyo leaves anything it isn’t sure of empty and says why. You can correct any answer before saving.
How reviewing worksSent to set up the form
- The blank fillable PDF
- Its instructions, if you add them
- Your note, if you add one
That’s all. They go to Fyllyo Cloud, or to your own OpenAI or Anthropic key. Setup never sees client data, and a test in Fyllyo’s code checks it. Keep personal details out of your note.
Stays on your Mac
- Your PDFs, scans, photos and notes
- Every filled form and your edits
AI form filling is 100% local, and works offline once the form is set up.
What setup costs
Setting up a form is paid with credits. $1 buys 100 credits, purchases start at $10, and credits never expire. The setup screen shows the credits a form will use before you start. If they run out, setup pauses instead of failing. Or use your own AI provider key instead.
Filling is covered by the one-time AI form filling licence, $99. There’s no subscription and no charge per fill, so a form you’ve set up costs nothing more to reuse.

Build your own document pipelines.
Bring together as many source files as your workflow needs. We’re building tools to let you define the steps with AI, run the pipeline locally, and create or update multiple documents in one run.
Fill specific Excel cells, generate PDFs, or transform other documents. You’ll choose the inputs, the logic, and the outputs.
Is your form already in the library?
Ready-made immigration, tax, court, benefits and business forms fill with no setup. If yours isn’t there, add it yourself or ask me to add it.
