This post is my submission for DEV Education Track: Build Apps with Google AI Studio.
What I Built
I created an On-Demand AI Coloring Book Creator — an app that generates unique, printable coloring book pages instantly based on any theme the user enters. I used Gemini to generate short, engaging captions for each page, and Imagen to produce black-and-white line art suitable for coloring. My key prompt was:
“Please create an app that generates unique, printable coloring book pages on demand. The app should allow users to enter a theme or keyword (e.g., dinosaurs, space fairies, underwater cats), generate a short caption using Gemini, and create black-and-white line art with Imagen suitable for coloring books.”
The app also features a simple, user-friendly interface that encourages creativity.

My Experience
Building this app was a fantastic way to explore how generative AI can bring creativity tools to anyone, even without design skills. I learned how to combine Gemini’s text generation and Imagen’s image creation seamlessly in a single workflow, all within Google AI Studio’s intuitive interface.
What surprised me most was how consistently unique and delightful the outputs were — even with repeated prompts on the same theme. It was also eye-opening to see how quickly an interactive and visually engaging app could come together with just the right prompt engineering.
