Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.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. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.
