Kai's verdictS-tier. If you're on Vercel/shadcn, this is cheating.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
