Kai's verdictA-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 for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier in the agent category. The first one I'd give to a non-technical friend.
