Kai's verdictS-tier. If you're on Vercel/shadcn, this is cheating.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.
