Kai's verdictS-tier. Category-defining UX. If you take notes in meetings, switch this week.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
