Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier. Category leader. Nothing else is close yet.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.S-tier for builders. The right primitives. What Kai is built on under the hood.
