Until now, adults drew the originals. From here on, kids can draw what they want to draw. We transform imaginative ideas—like a cat exploring space or a unicorn running on a rainbow—into beautiful line art. Print your creations and enjoy coloring them.
Original drawings created by visiting children at a booth during MITOU Conference (hosted by IPA). Unexpected ideas like "a dinosaur and a bullet train" made the event a huge hit.

From watching to creating
Turning children's screen time
from consumption into creation.
Videos, games, social media — in an age of endless digital content, children spend more and more time simply watching. Studies show 87% of parents worry about the quality of their child's screen time. We believe that by combining coloring — a beloved pastime for over 150 years — with generative AI, we can transform it from passively filling in someone else's lines to actively imagining and creating your own. AI Coloring was born to turn screen time from consumption into creation.
"I want to color a picture of a hammerhead shark riding a bullet train underwater!"
— We want to build a world where children's wildest ideas can come to life, just like that.
At exhibitions, we've watched children stay focused for over 40 minutes and light up at unexpected word combinations. "What should I create next?" — that natural loop of curiosity is exactly what AI Coloring is designed to spark. Our mission: deliver the safest, most creative AI experience for children. With a UI that even a 4-year-old can navigate, we're opening the door to creation for every child. A 150-year-old pastime enters a new chapter.

FAQ
Q1: How does AI-generated coloring work?
We use GPT-4o to create descriptive prompts from the selected keywords, cultural context, and age group, then send them to image-generation models (OpenAI DALL·E 3, Google Imagen 3) to output line art. We select the model based on its strengths.
Q2: Is it safe for kids? Can you prevent inappropriate images?
Yes. Safety is our top priority. We filter inappropriate words and rights-sensitive expressions with our own agent AI at the keyword stage, and image-generation models also have content filters.
Q3: Will it be paid in the future?
All features are currently free and unlimited to celebrate the launch. In the future, we plan a subscription model for the "generation" feature. However, coloring pages in the "Discover" tab and reusing uncollected pages will remain free so even free users can enjoy the app.
Q4: Who owns the copyright for generated coloring pages? Can schools use them?
Copyright for generated coloring pages belongs to Zukan.com Inc. Personal and household use is free. Educational use in school classes (including copying and distribution) is permitted under Article 35 of the Copyright Act. Please contact us for commercial or corporate use. See the Terms of Service for details.
Q5: Can we color directly inside the app?
An in-app coloring feature is coming soon. For now, you can print and color on paper. You can also transfer the image to a drawing app and color digitally.
Q6: Is there a feature to turn colored pages into videos?
We are actively developing this feature and already testing it in events.
