Kai's verdictA-tier for data teams. S-tier if you already live in SQL + Python.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
