Total creative control over AI image generation

ComfyUI is a node-based interface for AI image and video generation. Unlike simpler tools with a single text box, ComfyUI lets you connect processing nodes to build custom generation pipelines. Share workflows with others, install community plugins, and fine-tune every detail of the creative process.

FAQ

How is ComfyUI different from Stable Diffusion WebUI? WebUI is simpler — one text box, one button. ComfyUI gives you a canvas where you wire together processing nodes visually. It is more complex but offers far more control and uses less GPU memory.

Do I need to download models separately? Yes. ComfyUI uses the same model files as WebUI. Download checkpoint models from civitai.com and place them in the ComfyUI/models/checkpoints folder.

Is ComfyUI harder to learn? The node-based interface has a learning curve, but the community shares thousands of ready-to-use workflow files. You can download a workflow and start generating immediately without knowing how to build one.

Can ComfyUI generate videos? Yes. With plugins like AnimateDiff and CogVideo, ComfyUI can generate short AI videos and animations from text or images.
