The trade-offs
Strengths and Limitations
Kits.AI
Strengths
- Voices in the library are licensed from the artists, who are paid through revenue sharing
- Keeps your own melody and phrasing, because it converts a recorded take rather than generating one
- Stem splitter, vocal remover, harmony generator and AI mastering are part of the same subscription
- API for voice conversion, voice blending and vocal removal
Limitations
- Not a prompt-to-song generator: it needs a vocal recording to work from
- The free plan cannot download anything, and Starter allows only 15 download minutes a month
- Text-to-speech was withdrawn from the API in September 2025
- Unlimited conversions are stated to be subject to fair use
Soundful
Strengths
- Royalty-free licensing on every paid plan, with a Business licence for film, TV, advertising, apps and games
- STEM packs include a MIDI file alongside the separated stems
- Key and BPM are set before generation, so tracks fit an existing edit
Limitations
- No vocals, instrumentals only
- Free plan is one MP3 a month and cannot be used commercially
- The Music Creator licence is capped by audience reach, so growth forces a higher plan
