Frequently asked

Is AlertForge a replacement for Stable Diffusion?
Not really — they solve different problems. Stable Diffusion is open-source image model, while AlertForge is a streamer-specific tool for transparent alert overlays on Twitch, YouTube, and Kick.
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. Viewer Alerts is a separate Twitch-live flow with its own OBS browser source and Stripe Connect payout setup.
