| Kai's verdict | S-tier in its category. The first AI music tool I'd actually listen to. | B-tier. Still early. Manus is more flexible for less money. | A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google. | S-tier for open-source model APIs. The default in this space. |
