Kai's verdictB-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.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.
