Terms of Service
Last updated November 12, 2026
These terms are the agreement between you and marblecut.app ("we", "us") for using marblecut.app. By creating an account or making a video you agree to them. If you don't agree, please don't use the service.
What the service is
marblecut.app turns a song clip and a set of AI voices into a marble-race video, rendered in your browser. We don't host or store songs. Here's how songs work.
Your account
- You must be at least 13 years old, or older if your country sets a higher age for online services.
- Give a real email address and keep your password private. You're responsible for what happens under your account.
- We may ask you to confirm your email before you can make videos.
- You can delete your account at any time from the Account page.
Plans and limits
- Free: 1 video a week, free
- Plus: 7 videos a week, $5 a month
- Unlimited: no set weekly limit, $10 a month
Weekly limits count the videos you made in the last 7 days. A video that fails on our side doesn't count. Unlimited is subject to reasonable fair use so that one account can't use up shared capacity. Paid plans are subscriptions that renew monthly until cancelled. See billing and refunds.
What you may do
- Make videos for personal and social-media use.
- Post the videos you make on platforms like TikTok, YouTube Shorts and Instagram, as long as you have the right to use the music where you post it.
What you may not do
- Use the service to infringe anyone's copyright or other rights, or to impersonate a real person or artist in a way that deceives people.
- Make content that's unlawful, harassing, or sexually explicit, or that targets people for who they are.
- Scrape, resell or overload the service, bypass limits, or probe it for security weaknesses.
- Share your account, or create accounts to get around the free limit.
- Put someone else's name or picture in the creator badge. Use your own account only.
We may limit or close accounts that break these rules.
Third-party songs, voices and services
Song information comes from Apple's public search. AI voices are third-party voice models. We aren't affiliated with, or endorsed by, any artist, label, voice model creator, or platform. Names and artwork belong to their owners.
Your videos
You own the videos you make, subject to the rights of whoever owns the music and voices in them. Because videos are made on your device, we don't keep copies.
No guarantees
The service is provided "as is". Voices can sound different from what you expect, and a video may fail to render on some devices or browsers. We don't promise that the service will always be available or error-free. To the fullest extent the law allows, we aren't liable for indirect or consequential losses, and our total liability to you for anything relating to the service is limited to what you paid us in the 12 months before the claim.
Changes
We may update these terms. If a change is significant we'll tell you by email or on the site. Using the service after a change means you accept it.
