Krita Ai Diffusion
Open-source AI image generation plugin for Krita, free locally or via cloud
A must-try for Krita artists who want AI inpainting and composition control locally. The plugin is free, open-source, and offers unique control via sketches, depth maps, and poses. The cloud option is handy but lacks transparent pricing. It's not for non-Krita users or those needing mobile/API access. If you're committed to Krita, this is the best way to get AI assistance inside your painting workflow.

About Krita Ai Diffusion
Krita Ai Diffusion (also known as the Interstice Plugin) is an open-source plugin that brings generative AI directly into Krita, the professional painting application. It gives you precise control over AI-assisted painting, allowing you to generate, inpaint, and outpaint images using text prompts, selections, sketches, line art, depth maps, or pose skeletons. The plugin runs entirely on your local hardware for free, requiring a GPU, or you can opt for Interstice.cloud, an online service that removes the GPU requirement and makes AI painting accessible on lower-end machines. Designed for efficiency, it offers a minimal setup for basic operations while still providing advanced options for power users. The project is community-driven with its source code available on GitHub, and the team maintains a YouTube channel with tutorials. Krita Ai Diffusion is ideal for digital painters who want to integrate AI into their existing Krita workflow without switching to standalone tools. Compared to general-purpose AI image generators like Midjourney or DALL·E, it offers deeper integration with a professional painting app, but it is limited to the Krita ecosystem. Note that the cloud service's pricing and specific model names are not disclosed on the public site, so you may need to sign in or contact the vendor for details.
Behind the Verdict
Krita Ai Diffusion is a specialized tool that fills a specific niche: AI-assisted painting inside Krita. Unlike standalone generators like Midjourney or DALL·E, it doesn't just generate images from prompts; it gives you deep control over the generation process by letting you restrict changes to selected areas, use sketches, line art, depth maps, and pose skeletons as guides. This makes it particularly powerful for digital painters who want to iterate on their artwork without leaving their familiar environment. The local execution model is a strong selling point for privacy-conscious artists, though it requires a GPU. The cloud service, Interstice.cloud, lowers that barrier, but its pricing is not transparently published, which could be a sticking point for potential subscribers. The plugin is open-source, which means the community can inspect and improve it, and there's an active YouTube channel with tutorials. However, it's exclusively for Krita, so if you're using Photoshop or other software, this won't help. It also lacks API access and mobile support, limiting its use in automated pipelines or on-the-go. For Krita artists who want a seamless AI workflow with fine-grained control, this is the best option we've seen. Just be prepared for the GPU requirement or the opaque cloud pricing.

Where the pricing makes sense
The company stage and team size where Krita Ai Diffusion's pricing actually pencils out — and where peers do it cheaper.
The plugin is free for local use, which is ideal for hobbyists and professionals with a GPU.
