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.
VoiSona Song
VoiSona Song is AI voice synthesis software that reproduces human singing. It is available on iOS, macOS, and Windows, with a free editor and the Chis-A voice library available at no cost. Users can create vocals by entering notes and lyrics in a piano roll, importing MIDI into a DAW, or uploading MusicXML files. Editing controls cover phoneme timing, pitch, volume, vibrato, voice quality, and huskiness. On PC, the app can run on its own or as a VSTi or Audio Units plug-in. The iOS/iPadOS app runs standalone or as an AUv3 plug-in compatible with GarageBand, Logic Pro, Cubasis, and more. Export formats include WAV, MIDI, MusicXML, CCS, CCST, tsmsln, tssprj, and Lab; commercial use is allowed. Before a voice library is purchased, the free editor can make voices sing only the first 10 seconds of a song. Paid song voice libraries offer monthly, annual, and outright purchase options, with prices varying by library and displayed in yen. Sign-up is required, and an internet connection is needed for installation and some features. CeVIO Creative Studio and CeVIO AI exclusive voice libraries cannot currently be used.
