Krita AI Diffusion is a GPL-3.0 open-source plugin for the Krita painting app that adds Stable Diffusion / Flux-based image generation: text-to-image, inpaint, outpaint, refine, live painting, ControlNet/IP-Adapter guidance, regions, and upscaling to 4K/8K. It runs on a ComfyUI backend. Users can let the plugin auto-install a managed local ComfyUI, or in the Configure > Connection tab choose "Custom Server" and paste any ComfyUI API URL to connect to their own local or remote/cloud-hosted backend (e.g. a self-hosted box, RunPod, or RunDiffusion). The author also offers a first-party managed cloud, Interstice Cloud, as a pay-as-you-go token option for users who don't want to run GPUs themselves.

Why this trust score (85/100)

Trust measures how the tool treats your API key and how much of that has been verified. It contains no popularity signal.

  • Key Safety 23/25: The key is held on your own device.
  • Request Routing 17/20: Requests go straight from you to the AI provider.
  • Transparency 20/20: Source is public under GPL-3.0, so anyone can check how the key is handled.
  • Privacy 14/15: Local-first: it works without sending your data anywhere. Can be self-hosted, so the data path stays inside infrastructure you control.
  • Maintenance 10/10: Actively developed: commits within the last three months.
  • Verification Confidence 1/10: Compiled from public documentation by an AI-assisted pass, not independently confirmed.

How your API key is handled

Your API key is stored locally on your device. Requests are sent directly to the AI provider. Because it can be self-hosted, your key never has to touch a third-party backend.

Setup

Open settings, paste your provider API key, choose a model, and start. The key stays on your device.
