Kai's verdictA-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.A-tier in its niche. The only one that actually gets emotion right.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
