Labelling without manual work
The required label, the JSON-LD manifest and the QR code are set on save. Whoever writes the article does not need to know anything about Article 50.
Coming soon
AI labelling that
survives an audit.
AI Act Content Signer detects AI-generated content on save, labels it under Article 50 of the EU AI Act and signs it with Ed25519. For editorial teams, agencies and shops on WordPress, TYPO3, Shopware and Shopify – instead of manual label workflows.
- Label, JSON-LD and QR code land in your frontend automatically
- Every label can be verified through an open endpoint
- Detection returns a risk score – the decision stays with a human

What changes for you
Three things that cost manual work, guesswork or billable lawyer hours today.
Evidence that stays verifiable
Signature and audit entry can be checked at any time – by third parties too, without access to your system. A screenshot is not evidence. A signature is.
Stays in your infrastructure
SaaS in the EU or your own server via Docker Compose – air-gapped if you need it. Your content stays where you want it.
Three steps from draft to proof
No new editorial process – one more checkbox and a signature that holds.
-
Detect
Content is scored on save – with a calibrated risk score (measured: AUC 0.90 on our reference corpus) and a risk band instead of false certainty.
-
Label
Article 50 label, JSON-LD manifest and QR code go straight into the frontend – visible to readers, machine-readable for reviewers.
-
Sign
Ed25519 signature with monthly derived keys, plus a SHA-256 hash chain in the audit log. Later edits do not go unnoticed.

Durable, not just claimed
What holds is built to be verifiable – and what does not hold is not promised.
Ed25519 per RFC 8032
Signatures with monthly derived keys; the matching public key is available openly.
SHA-256 hash chain
Every audit entry chains the previous hash. A later edit breaks the chain.
Detection without exaggeration
The model returns a review signal, not a verdict. The durable layer is the signature – detection helps you prioritise.
