Kai's verdictS-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.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. Best for fast prototypes. Competitive with Lovable — try both.
