How do I make a hook and demo video?

Choose a reaction hook or add your own, upload one demo video, and optionally add centered hook text. Preview the result, then render and download it.

Do my videos stay private?

Yes. Your hook and demo files are inspected, previewed, and rendered in your browser. They are not uploaded or saved.

Which format will I download?

The tool prefers H.264 MP4. If your browser cannot render that combination locally, it falls back to VP8 WebM with the correct file extension.

Hook + demo video maker

Upload your product demo and get a ready-to-share reaction hook paired with it, with optional AI help writing the hook.

Add a demo video to start the preview

The hook plays first, then your demo. Hook text stays centered on the hook only.
