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 realtime. If latency matters more than voice catalog, start here.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for designers. The only one that takes vectors seriously.
