Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.S-tier for kids learning. The tutoring UX is legit — not a generic chatbot dressed up.S-tier for text-in-image. Use this for posters, Midjourney for art.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
