Kai's verdictS-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.S-tier in its category. The first AI music tool I'd actually listen to.S-tier for text-in-image. Use this for posters, Midjourney for art.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
