Kai's verdict	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.	S-tier infrastructure. The one platform every AI dev eventually uses.	A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.
