Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for realtime. If latency matters more than voice catalog, start here.A-tier for social/casual. B-tier for serious work. Good entry point.S-tier for search. I use it before Google now.
