Krita AI Diffusion is a plugin that integrates AI image generation into the open-source Krita digital painting software. It allows artists to blend AI-generated imagery with traditional digital painting techniques. The plugin uses Stable Diffusion, an AI model for image generation, within the Krita workspace. With Krita AI Diffusion, users can leverage text prompts and selection tools to generate new artwork, inpaint, outpaint, and refine existing images.

Key Features:

• AI-Powered Painting: Integrates AI technology to enhance digital painting and image creation.
• Inpainting: Allows users to select an area and remove or replace existing content using text prompts.
• Outpainting: Extends the canvas by filling blank areas with content that blends seamlessly with the existing image.
• Generate: Creates new images from scratch using text or existing images. Supports SD1.5 and SDXL.
• Refine: Refines existing image content instead of replacing it.
• Real-time diffusion effects: Applies diffusion effects in real-time, allowing for dynamic artistic adjustments. Also known as Live Painting, this lets AI interpret your canvas in real time for immediate feedback.
• User-friendly interface: Designed with a straightforward and intuitive interface.
• Customizable settings: Offers customizable settings to tailor the diffusion effects to specific artistic needs.
• Seamless integration with Krita: Works seamlessly within the Krita environment, enhancing the existing toolset without disrupting workflow.
• Support for multiple layers: Allows artists to apply AI diffusion effects to multiple layers.

Pros:

• Offers a wide array of brushes optimized for use with AI diffusion, enhancing texture and detail.
• Employs sophisticated algorithms for smoother and more natural color transitions.
• Capable of handling high-resolution images without performance lag.
• Includes step-by-step guides and tutorials within the tool.
• Actively updated to include the latest AI advancements and user feedback.
• Simplifies node setup, allowing artists to use Stable Diffusion directly on their canvas.
• Allows for adding consistent keywords to all prompts for a uniform style via the 'style prompt' feature.

Cons:

• Users new to digital art may find the integration of AI features in Krita complex.
• Lacks comprehensive guides and tutorials.
• AI features can be resource-intensive, potentially leading to slower performance on less powerful computers.
• Effectiveness and compatibility heavily depend on the updates from both the AI model and Krita itself.
• Optimal use of AI features may require advanced graphics hardware.

The plugin simplifies node setup, allowing artists to use Stable Diffusion directly on their canvas. The video discusses different connection methods, including a local managed server, custom server, and online service. Users can customize style presets, model checkpoints, and sampler settings to control image generation. Key settings in the diffusion settings include options to grow the selection and add a feather and padding to blend the newly generated part of the image with the rest of the image.
