Built to make ideas visual — fast

The problem I was solving

I kept running into the same situation: I had a PDF, a set of notes, or a long-form document that I needed to share with someone — but nobody was going to read a 15-page document. I needed a visual summary, but creating one in Canva or Figma takes 30–60 minutes of layout work even if you know what you're doing.

I wanted something that would take a document and turn it into a clean, shareable visual in under 30 seconds. When I couldn't find a tool that did exactly this, I built one.
