Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier for social/casual.
