3D AI Block Builder for Kids — Build Anything by Typing

A browser-based 3D building playground where kids type what they want — a castle, a dragon, a rocket — and watch AI build it block by block. 15 guided levels across 3 worlds (Nature, Fantasy, Sci-Fi) plus a free-build mode with unlimited blocks. Runs on phones, tablets, and computers with no signup required. Ages 6-15, completely free. Each creation can be saved, shared as a poster image, or used as the starting point for the next level.
