💡What is Krita AI Diffusion?

Krita AI Diffusion is a revolutionary 100% free open-source plugin created by Acly that embeds Stable Diffusion and ControlNet directly inside the popular Krita digital painting application. Instead of generating images in isolated web browsers, digital painters can generate, inpaint, upscale, and refine AI artwork using Krita's native layer stack, brushes, and selection tools. The plugin connects to a local ComfyUI backend for fast execution.
