Hometown Coloring Book
A sponsor-funded coloring book for West Michigan families, built end to end — including the AI pipeline that turns a sponsor's business into a custom coloring page.

What it is
Free coloring books for local families, paid for by the businesses in them. There’s no split between ads and content, because every ad page is a coloring page: a dance studio sponsors a page and gets a scene of kids dancing with a QR code to their site; a heating company gets its own scene. Families pay nothing. The sponsor pages fund the whole book.
I built it as 21 separate West Michigan editions — Grand Rapids neighborhoods, surrounding cities, and townships — each its own branded book. A sponsor buys a page by district, priced per copy from the district’s actual Census reach, so a bigger audience costs more.
The system I built
The core of it is the page-design pipeline. A sponsor sends a brief — text, a few reference images, their logo, a brand color, the URL the QR code should point to — and the system turns that into a print-ready coloring page.
The first round generates four different directions at once, each prompted to be visually distinct, so the sponsor is choosing a direction rather than approving or rejecting a single guess. After they pick one and comment, every following round generates a single new image, feeding the chosen image back to the model as a live reference alongside the feedback. It edits the picked image toward what they asked for instead of starting over — real image-to-image refinement, not a fresh roll of the dice each time.
The whole thing is prompted for a print-safe, sponsor-safe artifact, not just a nice picture: line art a 4-to-10-year-old can actually color, a corner reserved for the QR code, and no sponsor logo drawn into the art itself — that gets layered on separately. If the model keeps failing on a design, the job routes to me, so a sponsor’s page never just breaks.
Around that sit the parts a real business needs — checkout, sponsor accounts a team can share, an admin queue for anything that needs a human — built and operated by one person.
What happened
I ran cold outreach to local family-facing businesses starting in late April 2026, filling out contact forms one at a time so the pitch landed in an owner’s inbox like a customer inquiry instead of a spam folder. I did sell one — a business that committed to a page from that cold outreach. But it was only one.
Why I stopped
I didn’t take it to print. To scale it, the real job was door-to-door sponsor sales, city by city, across all 21 editions. That’s a field-sales operation, and building that company is a different thing from building the product. The product side worked; the AI pipeline, the checkout, the district system all did what they were supposed to. Scaling it meant feet-on-the-street local sales, which isn’t the work I want to spend my time on versus building software. So I proved the mechanism out and set it down.
