Retro Diffusion is an extension built specifically for Aseprite. Unlike generic AI art generators that output blurry images or downscaled graphics, Retro Diffusion uses custom-trained Stable Diffusion models designed strictly for pixel art.

Retro Diffusion requires a backend to process the AI generations.

Once installed, you have several ways to generate and edit art:

: The official Aseprite documentation includes a reference for the Lua API that Aseprite extensions use. This will be your guide for understanding what functions you can use to interact with Aseprite.

: Many developers and artists share their Aseprite extensions on GitHub. You can search for "Aseprite extensions" or specifically "retro diffusion extension" to see if someone has already created something you're looking for.

Start with your base pixel art in Aseprite. Open Extension: Go to Extensions > Retro Diffusion [1].

Downloading the script is easy; mastering it requires nuance. Here are three professional workflows.

Pixel art requires meticulous attention to detail, where every single square counts. For years, creators built these worlds pixel by pixel. Now, the bridges the gap between classic 8-bit aesthetics and modern generative AI.
