Kai's verdictA-tier for its niche. Different use case than Suno — SFX and loops, not songs.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier if you already pay Gemini. B-tier standalone.
