## FAQ

### What are the best free AI 3D model and CAD generators?

Flocci AI Tools lists 16 of them, ordered free tiers first: CADAM (Adam), Copilot 3D, Hunyuan3D-2 (Tencent), HunyuanWorld 1.0 and Step1X-3D. 15 of the 16 are free or have a free tier. Each entry states what it uniquely does rather than a score.

### Which of these are completely free?

7 on this page are marked fully free with no paid plan at all: CADAM (Adam), Copilot 3D, Hunyuan3D-2 (Tencent), HunyuanWorld 1.0 and Step1X-3D. The remaining 9 are freemium, trial or paid, and each is labelled with its exact tier so nothing surprises you at sign-up.

### How is this list ordered?

Free tools first, then freemium, then trial, then paid, and alphabetically inside each tier. Nobody pays to appear higher: Flocci AI Tools carries no ads, no sponsored slots and no paid listings, so the order reflects price and nothing else.

## Quick picks

### Which AI 3D model and CAD generators work in a browser with no install?

CADAM (Adam), Copilot 3D, Meshy, Polycam and Rodin (Hyper3D) all work in a browser tab with no install needed — just open the site and go. 10 of the 15 free AI 3D model and CAD generators listed here are browser-based.

### Which AI 3D model and CAD generators have a mobile app?

Meshy and Polycam have an iOS or Android app. 2 of the 15 free AI 3D model and CAD generators here can run on your phone.
