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.A-tier. S-tier if you self-host. The reason open-source image gen matters.
