Kai's verdictB-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.S-tier for solo + free. The best free option, hands down.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.
