Kai's verdictA-tier. Close second to Cursor. If $5/mo matters, start here.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for teachers. If you teach K-12, start here this week.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
