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 text-in-image. Use this for posters, Midjourney for art.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
