Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.S-tier for builders. The right primitives. What Kai is built on under the hood.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.A-tier. Genuinely different vibe from Suno — worth trying both for a month.
