Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.S-tier for speed. When latency is the product, start here.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.
