Kai's verdictS-tier for kids learning. The tutoring UX is legit — not a generic chatbot dressed up.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.S-tier for text-in-image. Use this for posters, Midjourney for art.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
