Check a 3D model for free
Drop a .glb from any text-to-3D or image-to-3D tool. You get a score in seconds — no account, and the file never leaves your computer.
How it works
Send us the output
The 3D your AI made — models, parts, scenes — or the 3D code and answers it wrote.
Automatic check
A program finds the obvious problems in seconds: holes, broken geometry, missing UVs, code that doesn't run.
A real expert looks
Geometry, dimensions, rigging, physics, style — what a program can't fully judge, reviewed by someone who does this for a living.
You get a score and a fix
A clear report for every output, and the corrected version back if you want it.
