76/100Safe BetFree planFreemium

If Krita is your painting app, this is the most direct way to get AI inpainting, outpainting and composition guidance into the canvas you already use. Selection-restricted generation is the killer workflow — edits land inside the area you chose, so you spend less time cleaning seams. Sketch, line art, depth/normal map and pose skeleton inputs give you control that prompt-only generators don't. The trade-offs are real: you're locked to Krita, local generation needs a GPU, and there is no standalone app. If you don't use Krita, look elsewhere rather than switching apps for this.

The 30-second take
Biggest gripe

Local generation is free, but it consumes your own GPU time and electricity, and slow hardware turns long renders into long waits.

Price reality

The plugin itself costs nothing and runs on your hardware, so the real comparison is your GPU versus a cloud generation service. Artists with a capable GPU get the strongest value here; artists on integrated graphics should weigh a cloud subscription against the price of a GPU upgrade.

In short

Krita Ai Diffusion — Open-source AI image plugin that brings inpainting, outpainting and composition control into Krita, running locally for free. Best for Digital painters already working in Krita, Concept artists who want sketch- and pose-guided generation, Artists with a GPU who prefer local generation. Free to use.

About Krita Ai Diffusion

FreemiumIntermediateNo APIDesktop · Plugin

Krita Ai Diffusion, also called the Interstice Plugin, is an open-source plugin that puts generative AI inside Krita, the professional painting application. You generate, inpaint and outpaint straight onto your canvas: restrict changes to a selection so new content fits the surrounding artwork, or fill, expand, remove and add content by prompt. Composition control is the part most other AI image tools do not offer — you can drive generation with a hand-drawn scribble, line art, depth or normal maps exported from 3D tools, or a pose skeleton you edit directly. The plugin runs on your own GPU and is free on local hardware; if your machine can't handle it, Interstice.cloud is a companion online generation service that removes the GPU requirement. The code is open source, with a GitHub repository, a Discord community and a YouTube channel of tutorials. It is built for digital painters who already work in Krita and want AI assistance without leaving their painting app. It is not a standalone web or mobile generator, and it does not work in Photoshop or GIMP.

Behind the Verdict

Krita Ai Diffusion's value is not that it generates images — plenty of tools do that better or faster — it's that generation happens inside a real painting application, on layers, next to your brush work. The selection tools are the strongest argument for it: fill, expand, remove and add content restricted to a selected region means generated pixels are matched to the surrounding artwork instead of pasted over it, which is the single biggest time sink in most AI-assisted painting workflows. The composition inputs are the second argument. Scribbles and line art let you keep your drawing as the structural basis for a render; depth and normal maps exported from 3D tools let you reuse an existing 3D scene as the geometry guide; pose skeleton editing lets you push a figure's anatomy around before generating. That's a much thicker control surface than a text box. The honest weaknesses: everything is gated behind Krita. Photoshop, GIMP, Procreate and Clip Studio users get nothing from it. Local execution wants a GPU — a real cost barrier for artists on laptops with integrated graphics, which is exactly why the Interstice.cloud service exists as a fallback for people who want the plugin without the hardware. The underlying generation stack is community open source rather than a proprietary model, so quality tracks the open-weight ecosystem rather than a single vendor's newest release. And this is a plugin, not a platform: there is no headless pipeline for scripted batch generation, no mobile app, and no browser-based canvas. Treat it as an extension of your painting desk, not a production automation system. Where it fits: illustrators and concept artists already in Krita who want to iterate on parts of an image — a hand, a background element, an extended canvas edge — without exporting to another tool and re-importing. Where it doesn't: teams that need consistent, auditable generation across many machines, or anyone whose pipeline is built around a different painting app.

Real-world workflow fit

Concrete scenarios for the personas Krita Ai Diffusion actually fits — and what changes day-one when you adopt it.

Freelance illustrator working in Krita on a desktop with a dedicated GPU

A client wants a figure moved and the background extended behind them. You select the figure region, run a remove-and-refill pass, then select the canvas edge and outpaint the background to fill the new area.

Outcome: The edits stay inside your selections, so the retouched region matches the surrounding brushwork and you avoid a full repaint of the background.

Concept artist sketching characters in Krita

You rough out a pose as line art, block in the silhouette, then use the pose skeleton controls to nudge the anatomy before running a generation pass over the sketch.

Outcome: The generated render follows the drawing and pose you set, which gives you several painted variations of the same concept instead of starting each one from scratch.

Artist on a laptop without a discrete GPU

You install the plugin, sign in to the Interstice.cloud image generation service, and run the same selection, inpaint and composition controls from your laptop.

Outcome: You get the in-Krita AI workflow without buying a GPU, at the cost of a cloud round-trip per generation.

Use Cases

  • Repaint or fix a hand, face or prop by inpainting only the selected region in Krita.
  • Extend the canvas edge of a finished painting with outpainted background.
  • Remove an unwanted object from a composition using a selection and a prompt.
  • Turn a rough scribble or clean line art into a rendered illustration pass.
  • Export depth or normal maps from a 3D tool and use them to guide an AI render.
  • Pose a skeleton to lock in anatomy before generating a figure.
  • Keep working entirely on your own machine when you have a GPU and don't want cloud round-trips.
  • Use the cloud service to run the same plugin workflow on a laptop without a dedicated GPU.

Models Under the Hood

Stable Diffusion (implied by 'image generation service')

as of 2026-09-22

Limitations

  • The plugin only works inside Krita, so if your studio standardises on another painting app this isn't an option.
  • Local generation requires a GPU; machines without one need the Interstice.cloud service instead, which is a different workflow with a sign-up step.
  • The generation stack is community open source rather than a single vendor's proprietary model, so output quality follows the open-weight ecosystem.
  • Control inputs (scribble, line art, depth, normal, pose) each add setup time compared with prompt-only generators — the payoff is precision, not speed.

Plugin (Local)

$0

Ideal for

Krita artists with a GPU who want AI inpainting and composition control without any recurring cost.

What this tier adds

Starting tier — free, runs on your own hardware, full inpainting, outpainting and composition controls.

Interstice.cloud (Cloud Service)

Sign-up required

Ideal for

Krita users on laptops or low-end machines who want the same plugin workflow without a dedicated GPU.

What this tier adds

Adds GPU-free cloud generation with a sign-up account, instead of rendering on your own hardware.

Hidden costs & gotchas

What the public pricing page doesn't put in bold. Captured from pricing-page footnotes, contract terms, and recurring complaints.

  • Local generation is free, but it consumes your own GPU time and electricity, and slow hardware turns long renders into long waits.
  • Composition workflows built on depth, normal or pose inputs assume you have a 3D tool or pose editor to produce them, which is separate software and separate learning time.

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 itself costs nothing and runs on your hardware, so the real comparison is your GPU versus a cloud generation service. Artists with a capable GPU get the strongest value here; artists on integrated graphics should weigh a cloud subscription against the price of a GPU upgrade.

Setup time & first value

How long it actually takes to get something useful out of Krita Ai Diffusion — broken out by persona, not the marketing-page minute.

If your GPU and Krita are already in place, most artists are through the installation guide and running a first selection-based inpaint within a single sitting. Expect longer on the cloud path, since it adds an account sign-up before your first generation, and longer again if you're new to depth, normal or pose inputs.

Switching to or from Krita Ai Diffusion

How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.

Migrating in
  • →From standalone AI image generators (Midjourney, DALL·E, Stable Diffusion web UIs): keep your Krita canvas and re-do the edit as a selection-based inpaint instead of exporting, generating and re-importing.
  • →From manual Krita retouching: replace clone-stamp and repaint passes over large regions with selection-restricted fill, expand, remove or add-content prompts.
  • →From a separate 3D render workflow: export depth or normal maps from your existing scene and feed them in as composition guides instead of rebuilding the lighting by hand.
Migrating out
  • ↗To a standalone AI image generator: you lose in-canvas selection control and keep the export-edit-reimport loop.
  • ↗To Photoshop with generative fill or another painting app's AI tools: you keep in-app editing but rebuild your brushes, layers and workflow in a new application.
