Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier if you're on Mac. The fastest way to get AI answers without context-switching.S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.
