Kai's verdict	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	A-tier. Bet on this one — the Sparkpage format is genuinely new.	S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.	A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.
