Kai's verdictA-tier for sales teams. B-tier for solo users.S-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.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
