Krita AI Diffusion

Krita AI Diffusion adds AI image generation to the painting workspace for artists who want to refine artwork without leaving Krita. It lets you direct changes through selections and visual input.

• Selected edits: Fill areas, extend a canvas, or add and remove objects while keeping changes within a selection.
• Composition control: Guide generation with sketches, line art, depth maps, poses and reference images, and assign separate text descriptions to image regions.
• Live painting and text edits: Get AI interpretations of your canvas as you paint, or modify an existing image with written instructions.
• Upscaling and history: Increase image size and detail, queue generation while you work, and revisit earlier results and prompts.
• Model choice: Use Flux 2, Z-Image, Stable Diffusion 1.5, Stable Diffusion XL or Illustrious, with custom checkpoints and LoRA presets.

The plugin is open source under GPL-3.0 and free to run on your hardware through ComfyUI. It supports Windows, Linux and macOS. NVIDIA, AMD and Intel GPUs work on Windows or Linux; Apple Silicon support requires macOS 14 or later. An NVIDIA GPU with at least 6 GB of VRAM is recommended. CPU generation is supported but very slow.

Interstice.cloud provides optional online generation that requires sign-up and doesn't need a local GPU. Choosing that service runs generation online rather than on your own hardware.
