Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier in the agent category. The first one I'd give to a non-technical friend.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.
