Kai's verdictS-tier for ad-hoc analysis. Makes you feel like a data scientist in 30 seconds.A-tier. Bet on this one — the Sparkpage format is genuinely new.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.
