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. Category-defining UX. If you take notes in meetings, switch this week.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.
