Frequently asked

Is AlertForge a replacement for OpenArt?
Not really — they solve different problems. OpenArt is multi-model image generation hub, while AlertForge is a streamer-specific tool for transparent alert overlays on Twitch, YouTube, and Kick.
Can OpenArt produce transparent video for OBS?
OpenArt'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.
