In their own words
Kits AI
Kits AI provides audio tools for creating and changing voices and working with vocals and music. Its features include voice cloning and conversion, vocal enhancement and removal, stem splitting, AI mastering, harmonies, pitch editing, and key and BPM detection. The voice-changing tools include a library of 100+ royalty-free artists. A Windows desktop app supports drag-and-drop into a DAW or other music production software and simultaneous auditioning of multiple vocal models; Kits AI is also available through a browser and API. The API lists voice conversion, blending, and vocal removal endpoints, while text-to-speech was deprecated from the API as of September 22, 2025. Kits says voices used in its models are licensed and sourced from artists, who benefit through revenue sharing. The free plan includes 15 conversion minutes, no voice slots, and no download minutes. Paid plans start at $10 a month. Submitted and generated audio may be used to improve the services, including related AI and machine learning models.
