A new app called Splat allows users to transform personal photos, pets, or everyday moments into black-and-white outlines for children to color. The app, from the creators of Retro, also offers educational themes and aims to provide a more personalized alternative to existing coloring pages. Splat operates on a subscription model, offering weekly and annual plans. It joins a growing market of AI tools for children, amidst ongoing discussions about AI's role in child development and skill-building.
