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.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.S-tier for open-source model APIs. The default in this space.
