Kai's verdictA-tier for its niche. Different use case than Suno — SFX and loops, not songs.A-tier. Best for teaching a kid to code in 2026.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.
