Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier. Category leader. Nothing else is close yet.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier for social/casual. B-tier for serious work. Good entry point.
