Copyright & how songs work
Last updated November 12, 2026
We don't host a song library. marblecut.app doesn't store, publish or sell songs. When you pick a track we fetch its audio for you, use it to build your video, and delete our working copy within 60 minutes.
Your finished video is rendered in your browser and saved to your device. It is never uploaded to us.
How a video gets made
- You search for a song. Titles, artists and artwork come from Apple's public search.
- When you press Make, our server fetches the audio for the clip you chose and sends that clip to our voice service, which re-sings it in the AI voice you picked.
- Your browser downloads the result, plays it while it draws the race, and records the video on your device.
- Our temporary audio files are deleted automatically, 60 minutes after they're created. We keep no archive of songs or of the voiced versions.
What we do keep
A short record that a video was made: the song title, artist, voices and date. We use it to count your weekly videos and to show you your recent voices. It holds no audio. You can delete it by deleting your account.
Posting your video
You're responsible for what you publish. Music is owned by artists, labels and publishers, and platforms like TikTok, YouTube and Instagram license music in their own ways. Check that you're allowed to post a song where you're posting it. We don't grant you any rights to a song, and nothing here is a licence to use one.
AI voices are models of a style of voice. Use them for fun and parody, not to deceive anyone or to pass a clip off as the real artist or person.
