Kai's verdictS-tier infrastructure. The one platform every AI dev eventually uses.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Genuinely different vibe from Suno — worth trying both for a month.A-tier for social/casual. B-tier for serious work. Good entry point.
