Kai's verdictA-tier if you already pay Gemini. B-tier standalone.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
