WeMotion is a free Mac app that turns one sentence into a motion-graphics film. Describe a launch film, product video, social clip or title sequence, and Motion, an AI motion designer built on Claude, builds the first cut layer by layer while it plays, then lets you direct it: pause anywhere, click what you want changed and leave a note, and Motion reworks it. Vibe mode keeps you out of the timeline entirely, while Pro mode opens every layer, keyframe and easing curve for hand editing. Motion can pull your brand from a link, compose an original soundtrack timed to the cuts, and export up to 4K at 60 frames per second using your Mac’s own hardware, so nothing uploads to the cloud. The app itself is free for Apple silicon Macs on macOS 13 or later; you bring your own Anthropic API key or Claude Pro or Max plan through Claude Code. It suits founders making a launch film, marketers producing social clips, and creators who want a directed film without learning motion design.
