Kai's verdictA-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.A-tier for data teams. S-tier if you already live in SQL + Python.
