Kai's verdictS-tier in its category. The first AI music tool I'd actually listen to.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.
