FAQ · AI content & watermarks
C2PA is a cryptographic provenance standard; its signed “Content Credentials” manifest is embedded in the file and tells platforms whether AI made it.
C2PA — the Coalition for Content Provenance and Authenticity — is a standard co-founded by Adobe, Microsoft, BBC, Sony and others that cryptographically signs a file with information about how it was made, including whether AI generated it. That signed manifest is called Content Credentials and is embedded as a JUMBF binary block inside PNG, JPEG and MP4 files. Tools like OpenAI’s Sora and DALL-E, and Adobe Firefly, attach it by default. Platforms such as Instagram and X can verify the signature in milliseconds and flag anything marked “made with AI.” It survives basic edits, so it has to be stripped deliberately.
