| Kai's verdict | A-tier for the right use case. Not for solo devs. If you manage engineers, try one license. | A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros. | 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. |
