Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.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.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.
