Turn your audience into part of the show. Viewers scan a QR code, draw in their phone browser, and send doodles to your OBS overlay. Approve each drawing or enable automatic display. Older drawings fade behind new ones, and the QR has its own source for flexible placement. No viewer app or account. One-time purchase; OBS and an internet connection required.
