Cardboard

An agentic AI video editor in your browser. Describe your edit and Cardboard cuts, captions, reframes, and composes it. No installs, no downloads. Hi! I'm your AI director. What do you want to make today? Cardboard watches your footage for you, finding the best moments so you spend less time digging and more time making videos. Turn one video into vertical, square, and landscape versions instantly. Cardboard keeps the important action in frame, so every version looks like it was edited by hand.
