Kai's verdictS-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
