WeMotion is a free Mac app for motion graphics. Describe a launch film and Motion builds it layer by layer while it plays. Pause any frame, leave notes, and it changes. Full timeline in Pro mode. Export up to 4K at 60 fps on your Mac. Apple silicon and macOS 13+ only. Use an Anthropic API key, or your Claude Pro or Max plan via Claude Code (free Claude plan does not work). Usage counts toward your own key or plan.
