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 open-source model APIs. The default in this space.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
