Kai's verdictS-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 coding. If you write code of any kind, this pays back the $20 in a day.S-tier. Category-defining UX. If you take notes in meetings, switch this week.
