Kai's verdictA-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier in the agent category. The first one I'd give to a non-technical friend.
