About Paperkin

Paperkin is an AI-powered children's coloring book generator built solo by Kirill Fraidine in Ottawa, Canada. The goal is simple: turn AI into a quiet, behind-the-scenes tool that produces hours of screen-free creative time for kids, not another app that competes for their attention.

Why Paperkin exists

Parents searching for coloring pages online today land in one of three places: huge ad-laden directories of stock printables; generic AI image tools that don't understand what age-appropriate line art looks like; or expensive printed books locked into a single theme. None of those serve the specific need of “I want a Triceratops coloring page that matches my 4-year-old's skill level, with their name on it, in the next 30 seconds.”

Paperkin is purpose-built for that exact use case. The age-calibrated detail slider, the kid-friendly font baked into every personalized title, the 16-language support, the print-ready 300 DPI output, and the KDP-compatible book builder all exist because the existing options weren't designed for parents who actually print and color with their kids.

Principles

• Screen-free output is the product. The app is a means; the printed page is the point. We optimize the generator, not engagement metrics.
• No advertising, ever.Children's digital experiences should be ad-free. Paperkin will never run banner ads or third-party tracking pixels.
• Honest, one-time pricing. Paid plans are one-time purchases, not subscriptions. You buy the tool; you own it.
• Your data is yours.Generation inputs and uploaded photos are never used to train third-party AI models without your explicit consent. We don't sell personal information.
• Print quality matters. 300 DPI, full-bleed, high-contrast line art. The page on your kitchen table has to look like a real coloring book page, not a screenshot.

The technology

Paperkin generates images through Google's Gemini Nano Banana Pro image model (gemini-3-pro-image-preview), wrapped in a children's-content-tuned pipeline that controls line thickness, shape count, and complexity per age group. The frontend is Next.js 16 running as a static export; the backend is FastAPI on Google Cloud Run; authentication runs through Firebase. Payments are processed by Stripe.
