Kai's verdictS-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.S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.
