Kai's verdict	A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.	S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	S-tier in its category. The first AI music tool I'd actually listen to.
