Kai's verdictA-tier. The most interesting spreadsheet in years. Great for ops dashboards.S-tier. If you're on Vercel/shadcn, this is cheating.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
