Kai's verdictA-tier. Best for teaching a kid to code in 2026.S-tier for designers. The only one that takes vectors seriously.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
