What it does
Collects the setup notebooks needed to run AUTOMATIC1111 or ComfyUI inside Google Colab, which lets you use a serious image-generation interface without owning a GPU - Google's hardware does the work. A browser and a Google account are enough. Google periodically restricts this kind of use on the free tier and cuts off long sessions, so whether it runs on any given day is not guaranteed and a paid Colab plan may be needed for reliability.
