Kai's verdictA-tier in its niche. The only one that actually gets emotion right.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.B-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.
