Kai's verdictB-tier. Still early. Manus is more flexible for less money.S-tier for kids learning. The tutoring UX is legit — not a generic chatbot dressed up.S-tier in the agent category. The first one I'd give to a non-technical friend.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
