Kai's verdictA-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.A-tier. Best for teaching a kid to code in 2026.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
