Kits AI is a suite of AI audio tools built for music production.

Related tools blend voices, design a voice from selected traits, generate harmonies and create speaking voiceovers from text. For audio clean-up and finishing, Kits AI includes a vocal remover with de-echo and de-reverb, a stem splitter for vocals, drums, bass and instruments, vocal enhancement, a key and BPM finder and AI mastering. There is also a library of AI instruments, a desktop app and an API for developers.
