Kai's verdictB-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.A-tier in its niche. The only one that actually gets emotion right.S-tier for solo + free. The best free option, hands down.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
