What you can build for YouTube
Alert workflows for YouTube and OBS
Super Chat alerts that feel premium
Generate a donation alert for Super Chat using your approved character reference and art direction, review it, then upload the selected WebM to the YouTube-connected alert widget you use.
Channel member welcome alerts
Use the subscriber and gifted-sub variants for channel-member moments, guided by the same character reference and art direction. Review each generated result before use.
Super Thanks recognition
Customize an alert title for Super Thanks and use the same approved reference to guide its media. Review the generated result with the rest of the set.
Works without YouTube's alert system
Use the generated media with StreamElements, Streamlabs, or another widget that connects YouTube events to OBS.
Portable alert media
Every AlertForge animation exports as a transparent WebM file you can keep locally and load through your existing alert widget.
