| Kai's verdict | A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class. | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | S-tier for text-in-image. Use this for posters, Midjourney for art. | S-tier for kids learning. The tutoring UX is legit — not a generic chatbot dressed up. |
