Kai's verdictS-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.
