Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.S-tier if you're on Mac. The fastest way to get AI answers without context-switching.A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs.B-tier. Still early. Manus is more flexible for less money.
