Ep 0 · I Decided to Build an AI Foodbook by Hand

Why an "AI foodbook" — built by hand

I didn't start with a pitch deck. I started with a bowl.

Foodbook (Korea: Geojibuk) is a meal RPG: three photos a day, rank up from the bottom, unlock better bowls and boards. The "AI" part is how the product gets designed — documents, gates, mocks — not a chatbot wrapper on calorie counting.

This series follows how that world got built: tiers, time windows, the Wheel of Fortune, and why we chose same game, two skins (Joseon and Medieval).
