Kai's verdictA-tier. Best for teaching a kid to code in 2026.S-tier for realtime. If latency matters more than voice catalog, start here.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. No reason not to use it if you're on Figma. Not worth switching for.
