Kai's verdictA-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.A-tier in its niche. The only one that actually gets emotion right.B-tier. Still early. Manus is more flexible for less money.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.
