Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier. Category-defining UX. If you take notes in meetings, switch this week.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.B-tier. Still early. Manus is more flexible for less money.
