Kai's verdictA-tier. Best for teaching a kid to code in 2026.A-tier. Close second to Cursor. If $5/mo matters, start here.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
