Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.S-tier for kids learning. The tutoring UX is legit — not a generic chatbot dressed up.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
