Kai's verdictA-tier. Best for teaching a kid to code in 2026.S-tier inside Photoshop (Generative Fill). B-tier standalone.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.
