What is Krita AI Diffusion?

An open-source Krita plugin that turns the painting workflow inside out: paint a rough composition, mask a region, hit generate, refine, repeat. Uses ComfyUI as the local backend so you can swap in any checkpoint, LoRA, or ControlNet. The preferred toolchain for digital artists who want diffusion in their existing canvas — not a separate Gradio tab.

Pros & cons

✓ PROS

  • Inpainting / outpainting / refine inside a real painting tool
  • Uses your existing ComfyUI install — no duplicate models
  • Live generation as you paint with the auto-refresh option

– CONS

  • Requires Krita 5.2+ and a running ComfyUI backend
  • Initial setup is fiddlier than a one-click installer

What's actually free?

GPL plugin; Krita itself is free and open.
