Weaknesses	Not for full songs with vocals Shorter generation limits	Developer-only You build the UI	Less agentic than Cursor/Claude Code Model quality varies	Bot-joining model Team features gated
Kai's verdict	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.	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	S-tier for solo + free. The best free option, hands down.
