| Kai's verdict | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement. | A-tier. The most interesting spreadsheet in years. Great for ops dashboards. | S-tier for realtime. If latency matters more than voice catalog, start here. |
