Was this made by AI?
Prove it — or disclose it.
Two free tools for the age of synthetic content: read the cryptographic provenance record inside any image or video, and generate the AI disclosures the EU now requires. Everything runs in your browser — nothing is uploaded.
Content Credentials Inspector
Drop an image or video and read its C2PA manifest: who signed it, which app made it, what was edited, and whether it declares AI generation. Powered by the official C2PA library compiled to WebAssembly — your file never leaves your device.

- The AI Act's transparency rules (Article 50) apply: chatbots must identify themselves, AI-generated content must be marked and deepfakes disclosed. Fines reach €15 million or 3 % of worldwide turnover.
- End of the transitional period: generative AI systems that were already on the market must also mark their outputs machine-readably.
- C2PA Content Credentials are shipped by Adobe, OpenAI and Google, and signed by newsrooms such as BBC, Reuters, AFP and ARD/ZDF — there is real provenance data inside more and more files. You just need a way to read it.
What are Content Credentials?
C2PA (Coalition for Content Provenance and Authenticity) is an open standard that embeds a signed record inside a media file: who created it, with which software, and what was done to it since. The signature makes the record tamper-evident — if anyone alters the file afterwards, validation fails. It is the closest thing the internet has to a nutrition label for media, and since Article 50 it is also one of the recognised ways to mark AI output machine-readably.
Frequently asked
Can this tool detect every AI image?
No — and no tool can. The inspector reads what a file declares about itself. If credentials are present, you get cryptographic certainty about who signed the file and what it claims. If they are absent, the file may still be AI-generated; absence proves nothing.
Is my file uploaded anywhere?
No. The C2PA library runs as WebAssembly inside your browser, and the site's security policy blocks requests to any other server. Your files, and your answers in the generator, never leave your device.
Is the disclosure generator legal advice?
No. It summarises Article 50 of Regulation (EU) 2024/1689 as general information and offers common wordings. For a binding assessment of your situation, consult a lawyer.
