What each one is
ComfyUI
ComfyUI is a node-graph interface for diffusion models that exposes every step of the generation pipeline, enabling complex, reproducible and shareable workflows.
- Total control via a visual node graph
- Reproducible, shareable workflows
- First to support new models and techniques
Krita AI Diffusion
This plugin brings Stable Diffusion and Flux directly into Krita: inpaint on layers, refine selections and live-paint with AI while keeping full artistic control.
- True layer-based inpainting in a pro painting app
- Live painting mode with instant AI feedback
- Uses a local ComfyUI backend — nothing leaves your machine
