Kai's verdict	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	A-tier. Close second to Cursor. If $5/mo matters, start here.	A-tier. Bet on this one — the Sparkpage format is genuinely new.	S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.
