Kai's verdictA-tier for its niche. Different use case than Suno — SFX and loops, not songs.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier. Still early. Manus is more flexible for less money.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.
