I spent 6 hours copying data from Excel to PDF manually. So I built an AI to do it for me.

Hey Product Hunt

I wanted to share a bit of what we ve been working on and get some early thoughts from this community.

SnapFill - AI form filling that keeps your layout 100% intact

SnapFill automates your most tedious paperwork：filling forms from research grants to legal docs. Manual entry is slow, and most AI tools break document layouts. SnapFill solves this by building a structured Knowledge Hub from your own files to fill new forms with deep context. Crucially, our engine guarantees Perfect Formatting: your output PDF or Word doc looks identical to the original, with tables, fonts, and styles perfectly preserved.
