A plugin that puts local image generation inside Krita, the open-source painting application. Because you are working on layers with real brushes, the workflow is the one artists already have — rough in a shape, generate over it, paint on top, generate again.

It drives ComfyUI underneath, either one it installs for you or one you already run.
