Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.S-tier in its category. The first AI music tool I'd actually listen to.S-tier for open-source model APIs. The default in this space.S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.
