Kai's verdict	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	A-tier in its niche. The only one that actually gets emotion right.	S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.	A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.
