If you love the idea of typing a prompt and getting a 3D model — but not the monthly bill — Polymosa is built for you. Pay only for what you make, keep your files forever, and start with 200 free credits.
All three turn a text prompt into a textured, export-ready 3D model. The difference is the business model — and what happens to your work when you stop paying.

You don't model 3D every day, so why pay every month? Buy a credit pack when you need one — a standard model costs a few cents.
Every model you generate downloads as a real file (GLB/STL/OBJ) that lives on your drive. Cancel nothing, lose nothing.
Auto-rig your character and export a rigged GLB — in the studio, at no extra tier. Great for game devs and quick prototypes.
Game props, printable minis, tabletop pieces — with a printability check and real physical-size export for 3D printing.
Type a description (or drop an image). Get a textured, export-ready 3D model in seconds. Download it, print it, or drop it into Unity, Unreal, Godot, or Blender.
Yes — you get 200 credits when you sign up, no card required. That's enough to make several real models before you ever pay.
No. Polymosa has no subscription. You buy credit packs (starting at $5) only when you need them, and they never expire.
