Kai's verdictS-tier. Category leader. Nothing else is close yet.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier for builders. The right primitives. What Kai is built on under the hood.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
