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