Kai's verdictS-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier for social/casual. B-tier for serious work. Good entry point.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
