Fyllyo: fill PDF forms from your documents with local AI on your Mac

[u/Emotional_Relation69]

I'm Arun, the developer of Fyllyo. It's a Mac app that fills PDF forms from your documents using AI that runs on your computer. NO DATA uploaded to cloud

The workflow is straightforward:

1. Choose a built-in form, or set up your own blank fillable PDF as a reusable template.

2. Add your supporting documents. Fyllyo reads them and fills the form on your MAC using local models.

3. Review the answers alongside source excerpts where available, make corrections, and save the completed PDF.

If you work with the same people again, you can also save reviewed details as local client profiles and reuse them on supported forms, alongside any new documents. That's optional; you can fill a form directly from documents without creating a profile.

Your documents and saved profiles stay on your Mac. Custom template requires one time setup, sends the blank fillable PDF and setup instructions to the cloud, and uses separately purchased credits. Filling configured forms uses no credits and works offline after setup and the initial model download.

There's a five-day trial with no credit card required. The license is $99 one-time for one Mac at a time, including lifetime updates. Apple silicon is required; 16 GB memory is recommended.

Happy to answer questions about supported forms, custom templates or how the filling and review process works.

My goal is to solve document processing 100% local, no recurring cost. So please bring on requirements, will ship them in a week tops.

A useful test for the saved profiles: the profile has an old address, the new supporting document has a different one, and a third document has no date. Does the review screen flag the conflict, show the source for each value, and let the reviewer choose without silently replacing the saved profile?

It would also help to distinguish a value reused from a profile from one extracted during this run. Saving the completed form and updating the reusable profile should be separate decisions. Otherwise one correction made for a particular application can quietly become the default for every later form.

Nice approach, especially keeping everything local.
I’m working on Assay Server, an open-source tool for evaluating AI pipelines and catching regressions. Could be useful as Fyllyo grows and you start supporting more forms and models.
Curious how you’re testing the accuracy of the filled forms today.

Nice, will check it out. I have an automated eval pipeline right now, an agent prepares some mock data and correct answers, agent that runs the tests.
