FAQ

Do I need to pay to use AI in game development?

No. Many of the tools here have a free tier, and some (like ComfyUI and Hunyuan3D-2) are open source and run locally. Paid plans mostly add volume, commercial terms and team features.

Can I ship AI-generated assets in a commercial game?

It depends on each tool's license and your plan tier, and some storefronts ask you to disclose AI content. Check the terms on the tool's site and your platform's rules before you ship.
