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.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
