How to check if an image was made with ComfyUI
- ComfyUI embeds the node graph ("prompt" and "workflow") in every PNG it saves.
- We detect those chunks and pull out the checkpoint or UNet model name, such as an SDXL or FLUX file.
Visual signs of ComfyUI content
ComfyUI is a front-end, so the look depends on the model. The embedded workflow is the reliable signal.
Visual clues are never conclusive on their own. Combine them with a metadata check and a reverse image search. See our full guide: how to tell if an image is AI-generated.
ComfyUI detector FAQ
Can I recover a ComfyUI workflow from an image?
The workflow is stored in the PNG. Our tool confirms it is there and names the model; you can also drag the PNG into ComfyUI to load the full graph.
