Weaknesses	Not for full songs with vocals Shorter generation limits	UX is rough for English speakers Queue times	Less agentic than Cursor/Claude Code Model quality varies	Slow vs doing it yourself Breaks on complex auth flows $200/mo gate
Kai's verdict	A-tier for its niche. Different use case than Suno — SFX and loops, not songs.	A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	B-tier. Still early. Manus is more flexible for less money.
