Kai's verdict	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.	A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.	A-tier in its niche. The only one that actually gets emotion right.
