Kai's verdictS-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for open-source model APIs. The default in this space.
