Kai's verdictB-tier. Still early. Manus is more flexible for less money.S-tier in the agent category. The first one I'd give to a non-technical friend.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
