Real 3D artists, checking what AI builds.
AI is learning to make 3D — and to write the code and answers behind it. Most of what it produces is still broken. Harpoon gives AI labs an automatic quality check plus real 3D artists to test it, score it and fix it.

How it works
Send us the output
The 3D models your AI made — or the 3D code and answers it wrote.
Automatic check
A program finds the obvious problems in seconds: holes, broken faces, missing UVs, code that doesn't run.
A real artist looks
Shape, topology, rigging, style — the things a program can't judge, reviewed by someone who does this for a living.
You get a score and a fix
A clear report for every model, and the corrected model back if you want it.
