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. Close second to Cursor. If $5/mo matters, start here.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.
