What it is
Kits AI provides audio tools for creating and changing voices and vocals, with features for music production. The tools include voice cloning and conversion, vocal enhancement and removal, stem splitting, AI mastering, harmonies, pitch editing, and key and BPM detection. A library of 100+ royalty-free artists is available for AI voice changing. The Windows desktop app supports drag-and-drop into a DAW or other music production software and lets users audition multiple vocal models at once; browser access is also listed. API endpoints cover voice conversion, voice blending, and vocal removal, but text-to-speech was deprecated from the API on September 22, 2025. Kits says model voices are licensed and sourced from artists, who benefit through revenue sharing. Submitted and generated audio may be used to improve its services, including related AI and machine learning models. The free plan includes 15 conversion minutes, no voice slots, and no download minutes. Paid plans start at $10 a month; Starter includes unlimited conversions, two voice slots, and 15 download minutes.
