| Kai's verdict | A-tier for ops automation. B-tier for simple copy (use Claude). | A-tier for the right use case. Not for solo devs. If you manage engineers, try one license. | S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement. | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. |
