Kai's verdictS-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.A-tier for sales teams. B-tier for solo users.
