Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier for academic research. Nothing else comes close for systematic reviews.S-tier for search. I use it before Google now.
