Kai's verdictB-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.
