Natafill turns any PDF into a fillable form. Upload a document that has form fields drawn on it but no interactive input areas — a tax form, a contract, an intake form — and the AI detects every text box, checkbox, radio button, and signature area. Download the result as a working fillable PDF. Free to use with a small watermark, or sign in to remove it.
For a while, I kept noticing the same pattern in Indonesian businesses: they run on paperwork. Insurance claims, patient intake, KYC forms, contracts — most of it still lives in PDFs that customers have to print, fill by hand, scan, and email back.
The existing tools didn't fit. Google Forms was too basic and didn't tie back to the official document. Typeform felt built for a different world. Rebuilding forms in Acrobat Pro was slow and expensive.
Nataform started as an answer to that: a form builder where you build a friendly digital experience on top of the official PDF. Customers get a modern form. You still get back the exact document you need — signed, timestamped, ready for compliance.
The thing I underestimated: how much of the work was just making it feel simple. The AI field detection, the conditional visibility rules, the drag-and-drop editor — those all came from watching people who weren't developers try to use the first version and giving up.
Still shipping. Would love to hear what forms slow your team down the most.
