Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.A-tier. Genuinely different vibe from Suno — worth trying both for a month.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
