Transparency & Technical Note
We believe in full transparency regarding AI tools. While our extension removes the visible watermark overlay for aesthetic purposes, it respects the underlying digital provenance.
C2PA Metadata Notice
Videos generated by Sora contain invisible C2PA (Coalition for Content Provenance and Authenticity) metadata. Our extension does not strip this metadata. This ensures that platforms can still identify the content as AI-generated, maintaining ethical compliance while giving you a clean visual output.
