Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Best for fast prototypes. Competitive with Lovable — try both.A-tier in its niche. The only one that actually gets emotion right.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
