Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier all-rounder. If you want one tool that does everything okay-to-great, this is it.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier for kids learning. The tutoring UX is legit — not a generic chatbot dressed up.
