Showoff is an editor for launch videos, App Store screenshots and device mockups. You can work on a project alone, with your team, or with your AI, all at the same time. Connect Claude through our MCP server and ask it for a first draft. You see it build the project in the editor, then you or a teammate change whatever you don't like. Your screenshots go onto real 3D iPhones, iPads and MacBooks, and the video is cut to the song you upload.
