Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-tier. Best for fast prototypes. Competitive with Lovable — try both.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
