Kai's verdictA-tier. Close second to Cursor. If $5/mo matters, start here.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
