Document Filler

AI-powered document field detector and form filler — upload any PDF, get a clean form to fill it out, download the completed document.

Why I built this

I got tired of opening PDFs in clunky viewers just to fill in a few fields. I wanted something that felt like filling out a modern web form, no matter how messy the source document was.

How it works

• Upload a PDF and the app detects existing form fields automatically
• For documents without fields, you can drag-and-drop your own field zones onto the page
• Fill everything out in a clean, ChatGPT-style sidebar form with text that auto-scales to fit
• Download the filled PDF, or save it to your account to revisit later
