Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-tier for creators training custom looks. B-tier for general use.S-tier for model-shopping. I use this for every prototype before committing.S-tier in its category. The first AI music tool I'd actually listen to.
