Kai's verdictS-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.S-tier for kids learning. The tutoring UX is legit — not a generic chatbot dressed up.A-tier for data teams. S-tier if you already live in SQL + Python.
