Every option in the catalog for when you need to turn a prompt or photo into a usable 3D asset — 16 AI 3D model and CAD generators, 15 of them free or freemium, with the pricing tier printed on every row.
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.
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.
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.
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.
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.
Hunyuan3D-2 (Tencent), Step1X-3D, TRELLIS (Microsoft) and TRELLIS.2 (Microsoft) can be self-hosted or run locally without a browser — useful for privacy, air-gapped networks, or avoiding API rate limits. 4 of the 15 free AI 3D model and CAD generators here run offline.
