Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.B-tier. Still early. Manus is more flexible for less money.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.
