Kai's verdictB-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.S-tier. If you're on Vercel/shadcn, this is cheating.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. No reason not to use it if you're on Figma. Not worth switching for.
