06 WHY_I_BUILT_THIS

"AI is great at creating content. Not great at taking it on the road."

I use AI for meeting prep, checklists, and reference guides. But I wanted something I could print, fold, and not worry about losing. So I built a way to turn AI answers into pocket reference cards. No app. No battery. Just paper.
