Kai's verdictS-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.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.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.
