Kai's verdictS-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier. Granola is better UX but Otter works everywhere. Pick based on your platform.A-tier. Best for fast prototypes. Competitive with Lovable — try both.
