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. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.S-tier for academic research. Nothing else comes close for systematic reviews.
