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.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.
