Kai's verdictS-tier for solo + free. The best free option, hands down.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.A-tier for social/casual. B-tier for serious work. Good entry point.
