Kai's verdictB-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.S-tier. Category leader. Nothing else is close yet.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.
