Kai's verdictS-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.A-tier for sales teams. B-tier for solo users.B-tier. Still early. Manus is more flexible for less money.
