Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.A-tier. S-tier if you self-host. The reason open-source image gen matters.
