Built from a notebook, one page at a time
Before there was an app, a kit, or a plan — there were 31 handwritten pages, and a working partner to build it out with.
Tania spent months working the idea out by hand — how the app choices map to physical pieces, why the clear pocket page had to be the album page and not a separate object, why shipping had to disappear entirely for this to work at library and park pickups.
Turning that notebook into an operating plan, a mission document, and a three-scenario financial model happened in conversation with CAT — Claude Agent for Tania: reading the photographed pages, drafting each document, and rebuilding sections whenever Tania caught something the draft had gotten wrong against her own notes.
One of those catches: an early financial model overstated the workforce program's staffing cost by 5x. Tania traced it back to the notebook and had CAT correct it — a small example of the back-and-forth that shaped every document here.
This page, the documents above, and the process itself are part of an article Tania is writing on working with CAT — so other founders without a business background can see exactly how an idea moves from notebook to nonprofit.
CAT is Tania's name for her working sessions with Claude, Anthropic's AI — not a separate product.
