Kits AI
The one voice-conversion tool that took licensing seriously — artist models are opt-in and paid, so releases built on them are less likely to blow up legally. Post-Splice acquisition, expect the standalone product to keep running but the interesting roadmap to land inside Splice's own ecosystem.
Pros
- Models trained on fully licensed data with an artist approval step before commercial release
- Full vocal chain around conversion: stem split, remover, repair, generative vocals
- Public API docs, rare in this category
- Now backed by Splice, so funding and catalog access are no longer a risk
Cons
- Free tier has zero download minutes — you can hear results but not keep them
- Voice slots are gated by tier, so training several models pushes you to $30+
- Professional cloning quality needs clean, well-recorded input; noisy takes convert badly
- Acquisition means product direction now answers to Splice's roadmap
