Kai's verdictS-tier for solo + free. The best free option, hands down.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.
