Kai's verdictS-tier all-rounder. If you want one tool that does everything okay-to-great, this is it.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.A-tier. Best for teaching a kid to code in 2026.
