Kai's verdictB-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier for kids learning. The tutoring UX is legit — not a generic chatbot dressed up.B-tier. Still early. Manus is more flexible for less money.
