What is Retro Diffusion?
This extension for the popular pixel art software Aseprite allows the easy installation and use of Stable Diffusion AI image generator from inside Aseprite. It also adds advanced features like smart color reduction, and text guided palette creation. In combination with the state of the art pixel model, you can design incredible pixel art pieces in record time.Learn More
You can try it out by creating an account at retrodiffusion.ai. When you sign up you will get 20 free credits to create images with. You do not need to buy credits for the Aseprite extension version.

Custom pixel art AI model
Retro Diffusion comes with its own pixel art model, which returns results astronomically better than any competing model or AI. If you have tried to get Dall-e 2, Stable Diffusion, or even Midjourney to create accurate pixel art before, you know that they just don't get it.
The best part is, this model has been trained on licensed assets from Astropulse and other pixel artists with their consent.
Select the pixel art model and watch as near perfect pixel art is made in seconds!

Convert any image to pixel art
Using the "Neural Pixelate" tool, easily turn images into pixel art versions with style accurate colors, or choose to keep the original colors!
Transform your art
Traditionally, resizing pixel art doesn't produce good results, as it either destroys detail when downscaling, or makes the image blurry or blocky when upscaling. "Neural Resize" allows you to change the size of pixel art image and generate entirely new details.
You can also use "Neural Detail" to add higher levels of detail to simple pixel art designs.
Using a unique pipeline, Retro Diffusion allows you to control lighting, colors, and other image features from an ultra-simple interface.
These settings are applied in-generation, not as post processing effects. This allows the images to change and adapt to the color and lighting conditions.
Large Language Model Prompt Helper
We also leverage the abilities of a LLM to make prompting dead simple. Type anything, and it will be converted into the best format for the image generator to understand. You can even just ask for "something" and the AI will invent amazing ideas for you!
Several models have been developed specifically for Minecraft style assets, making developing good looking mods and resource packs easier than ever!
All these assets took under an hour to create, with most of the time spent generating images.
Additionally, if you enable the "Tiling" modifier, you can create beautiful seamless block textures in record time.
I also have a great tool for Aseprite that lets you see a freely rotating 3D block in your editor window: https://astropulse.gumroad.com/l/BlockPreview
Generate creative and interesting game assets just by describing them, no more need for dreaded 'programmer art.'
Using the Palettize feature, you can easily reduce the number of colors in an image, or change the colors entirely in just a couple clicks.
Built in styles
Retro Diffusion has different pixel art styles available at the click of a button. In addition to the "Game item" and "Tiling" modifiers there are:
Including NES, SNES, Game Boy, Game Boy Advance, NeoGeo, and PlayStation styles.
These modifiers can even be applied at different strengths to achieve different styles!
Pixel Art Background Removal
Quickly and easily remove backgrounds in one click.

* Linux support is not guaranteed. The number of distros, environments, and the commonality of user system modifications makes assured support next to impossible. Retro Diffusion has been tested on stock Ubuntu, Mint, and Fedora. Customized versions of these distros may not be supported. If you have any issues with compatibility on Linux be sure to contact me directly via Discord.
