Kai's verdictB-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.A-tier for social/casual. B-tier for serious work. Good entry point.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for builders. The right primitives. What Kai is built on under the hood.
