Karatrack+AI is professional karaoke hosting software for Windows, built by working KJs for bars, venues and mobile hosts. It runs the entire show from one console: automatic singer rotation, dual DJ decks with EQ and volume normalization, a branded singer screen with album art, and live song requests from singers' phones through the free Karameet app or an in-venue Karakiosk. Industry-first tools include linked singers for duets and groups, singer self-reorder, identity merging to stop rotation cheating, and remembered fade-in/fade-out points for every track. On-the-fly vocal removal uses NVIDIA CUDA. The host console, singer screen and kiosk support 13 languages. Sold as a one-time lifetime license with free updates; the core hosting tools run offline during a show. Part of the Karatrack suite alongside Karatrack Library Manager and Karatrack Studio.
