Kai's verdictB-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.B-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
