What this service is
Seedance Check is a free tool that queries the official ModelArk artifact verification API to check whether a video carries official Seedance artifact signals. Daily usage limits apply per device, per network and site-wide to keep the service available.
Results are reference only
Verification results are produced by automated analysis and are provided as-is, without warranty of any kind. A result is not a legal, forensic or copyright determination, and a negative result does not prove a video is not AI-generated. You are responsible for how you use the results.
Acceptable use
Upload only videos you have the right to process. Do not submit unlawful content. Do not scrape, bulk-query, resell or otherwise abuse the service; we may throttle or block abusive traffic.
Third-party services and trademarks
Checks are processed by the official Volcengine and BytePlus ModelArk APIs under their own terms. Seedance, ModelArk, Volcengine, BytePlus and related marks belong to their respective owners. This site is an independent third-party tool and is not affiliated with, endorsed by, or operated by ByteDance.
Sponsorship
This site is sponsored by Renoise. Sponsorship never affects verification results, which come directly from the official API, nor the aggregated statistics we display.
