Kai's verdictA-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.A-tier. Close second to Cursor. If $5/mo matters, start here.
