Kai's verdictA-tier for data teams. S-tier if you already live in SQL + Python.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.A-tier. S-tier if you self-host. The reason open-source image gen matters.
