Kai's verdictA-tier. The right answer if you want open-source + terminal-native + model-agnostic.A-tier if you already pay Gemini. B-tier standalone.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.B-tier. Still early. Manus is more flexible for less money.
