HyperFrames Studio is a desktop video editor built specifically for AI coding agents, created by the team behind the open-source HyperFrames framework at HeyGen. Users describe a video, an AI agent builds it using HTML, CSS, and JavaScript, and both the user and agent work on the same shared timeline. The Studio provides a visual surface with live preview, hot reload, a property panel, source editor, and file browser, with all changes written back to editable project files rather than flattened exports. It is available as a native app for macOS and Linux, with Windows support coming soon, and includes hundreds of templates and the ability to draw or comment on frames to direct the agent's edits.
