| Kai's verdict | B-tier. Still early. Manus is more flexible for less money. | S-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. | B-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency. |
