Kai's verdictA-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.B-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.
