Frequently asked

Is AlertForge a replacement for Stable Diffusion?
That depends on what you use Stable Diffusion for. AlertForge creates stream graphics and animations. It does not replace your broadcasting software or the alert widget that connects to your streaming platform.
Can Stable Diffusion produce transparent video for OBS?
Stable Diffusion's supported output depends on that product. AlertForge exports transparent WebM with VP9 alpha for an OBS Media Source or custom-media alert widget.
How do AlertForge alerts trigger on stream?
Upload an AlertForge WebM to the platform-connected alert widget you already use, which handles follower, subscriber, donation, or raid events.
