Kai's verdictS-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier for solo + free. The best free option, hands down.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
