Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.B-tier. Still early. Manus is more flexible for less money.S-tier for realtime. If latency matters more than voice catalog, start here.S-tier inside Photoshop (Generative Fill). B-tier standalone.
