Kai's verdictS-tier in its category. The first AI music tool I'd actually listen to.A-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.S-tier for text-in-image. Use this for posters, Midjourney for art.
