Kai's verdict	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.	B-tier. Still early. Manus is more flexible for less money.	A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.
