Kai's verdictS-tier infrastructure. The one platform every AI dev eventually uses.A-tier. Best for fast prototypes. Competitive with Lovable — try both.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.
