Kai's verdict	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	A-tier for real-time. B-tier for everything else. Worth checking when news breaks.	S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.	S-tier all-rounder. If you want one tool that does everything okay-to-great, this is it.
