Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.S-tier in its category. The first AI music tool I'd actually listen to.S-tier in the agent category. The first one I'd give to a non-technical friend.
