Built for working karaoke hosts. Nobody argues with the rotation. Retire the clipboard and paper slips. Auto-KJ is the modern show-running system powered by the Fairness Engine — keeping every rotation 100% fair, eliminating duplicate songs, balancing group duets, automixing break music, and letting singers submit requests directly from their phones. Free version for Windows, macOS, and Linux, with a 60-day trial in the app and no card.
