Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier in its niche. The only one that actually gets emotion right.S-tier if you're on Mac. The fastest way to get AI answers without context-switching.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
