The label is gone, the obligation remains
One screenshot is enough and the AI image keeps circulating unlabeled. With on:mint, you can prove at any time that you labeled your asset correctly.
Label AI content. Get the obligation right.
As of August 2, 2026, the EU AI Act requires AI content to be labeled. Visible to people, readable by machines. on:mint handles both, adapted to your own standards.

Labeling is mandatory.
Proving is better.
Since August 2026, AI content must be labeled: in machine-readable form by providers, visibly by deployers. But a visible label can be removed, overwritten or cropped out, and many lack the infrastructure for technical marking. Either way, the question remains: how do you prove that you labeled correctly?
Machine-readable is easier said than built
The AI Act requires marking that is effective, interoperable, robust, and reliable. Building that yourself takes months – and the standard it will be tested against is only just emerging.
The chain breaks at the first download
AI provider, agency, brand, marketplace: every station must meet its own obligations. Without provenance information traveling with the asset, no one can reliably tell what is AI and what was changed.
If you use AI, you have obligations. The question is which ones.
Whether you offer an AI tool yourself or only use AI for your own content, the EU AI Act treats those cases differently, and most companies can't tell at a glance where they stand. The self-test asks a few simple things about how you use AI and then tells you what applies to you. It's free, no sign-up, no prior knowledge needed.
Content Credentials
Content Credentials are the technical form of AI labeling: a signed, machine-readable disclosure embedded directly in the file. It documents that a piece of content is AI-generated, who created it, and what has been changed. on:mint creates the credentials automatically at upload or via API, signs them to the C2PA standard, and anchors them immutably. That puts the machine-readable marking required by Article 50(2) in place, and your labeling stays verifiable for humans: one click on the Cr icon is all it takes.
01
For deployers: your AI label becomes provable
The visible disclosure is secured cryptographically and steganographically. If the label is removed or altered, this is immediately detectable. Compliance you can prove.
02
For providers: machine-readable from the source
Via the API, every output is automatically marked C2PA-compliant and detectable — exactly what Article 50(2) AI Act requires. No in-house development, with usage metering.
03
Credentials travel with the asset
Every station in the value chain — from AI provider through agency to marketplace — reliably sees what is AI and what was changed, and can meet its own obligations.
04
Trust becomes verifiable
One click on the Cr icon or the AI label reveals the full provenance history – like a seal of authenticity anyone can check. This protects AI assets as much as digital originals.
05
Your labeling is verifiable everywhere
The browser extension reads C2PA credentials across the web and shows whether an asset is on:mint-verified and labeled as AI. Your labeling stays visible even where platforms don't display it.
See how anyone checks your label. One click is enough.

Why you can rely on on:mint
01
We are a C2PA issuer
On upload, Content Credentials are created automatically, cryptographically signed, and steganographically secured – in C2PA, the open, interoperable industry standard backed by Adobe, Microsoft, and major platforms. No proprietary format, no lock-in.
02
One upload, both labels
The EU AI Act wants a notice people can see and a mark machines can read. on:mint applies both automatically at upload. From then on, your asset carries its label with it, even after it's downloaded and passed along.
03
Legally grounded
Developed with the attorneys of tech law firm Schürmann Rosenthal Dreyer. Your labeling doesn't just meet the obligation visually – it holds up as compliance evidence. With on:mint, your company has a legal tech tool at hand to set its own labeling standards and implement them cleanly.

AI labeling for providers, deployers and everyone in between.
Article 50(2) requires providers of generative AI systems to mark all outputs in a machine-readable format. Via our API or MCP, you mark every output automatically – C2PA-compliant, robust, interoperable, with usage metering.
Helps you meet the technical marking obligation via API
Using AI images in campaigns, social media or your shop? As a deployer, you have had to visibly disclose deepfakes since August 2026. With on:mint, your label is secured and your labeling is provable.
Makes your disclosure provable
Producing AI content for clients? Sign assets before delivery. Your clients reliably see what is AI and what was changed — and can meet their own obligations.
Deliver with legal certainty, and trust included
AI-generated on-model images increasingly replace photoshoots: products are transferred to virtual reference models via AI and circulate in shops and on platforms. The platform adds the machine-readable marking, the shop and brand disclose it visibly — and a signature always makes clear which asset truly came from which production.
Secures the whole chain, from production to shop
Sign and verify entire image collections in batch: what's real, what's AI, what was changed? Ideal for migrating holdings ahead of the deadline.
Brings holdings into a provable state
The labeling obligation is already in force.
In force since August 2
Anyone publishing AI content that could pass for real has had to disclose it visibly since August 2, 2026. Providers of generative AI systems have until December 2, 2026 to put machine-readable marking in place. Violations can be fined up to €15 million or 3% of worldwide annual turnover.
Platforms are moving first
LinkedIn and other platforms already display Content Credentials; the EU is working on a standardized AI label. Sign now and be compatible before everyone else is.
Your assets are already circulating
AI images sit in shops, campaigns and on marketplaces, mostly without provable provenance. What goes out unsigned today can't be proven after the fact.

FAQs
Since August 2, 2026. Providers of generative AI systems must mark outputs in a machine-readable format, recognizable as artificially generated or manipulated (Art. 50(2)). Deployers must disclose deepfakes in a perceivable way, as well as AI-generated text on matters of public interest published without editorial responsibility (Art. 50(4)) – at first exposure at the latest, clearly recognizable, not in the fine print. For the machine-readable marking under Art. 50(2), providers of generative AI systems have until December 2, 2026 to put the required measures in place.
Providers develop an AI system or place it on the market under their own name; deployers use it professionally under their own responsibility. Important: even companies that merely use AI tools – say, a brand or agency creating and publishing AI images – count as deployers and carry the obligation. As a provider, you implement machine-readable marking with on:mint via API or MCP; as a deployer, you secure your visible disclosure cryptographically and steganographically and can prove it at any time.
It meets the disclosure obligation — but it is only a claim: removable, overwritable, undocumented. If the asset keeps circulating without the label, you lack proof that you labeled it correctly. Content Credentials make labeling tamper-evident and provable.
Content Credentials are the tamper-proof passport for digital assets: a signed, machine-readable provenance record documenting who created an asset, with which tool, and what was changed. The foundation is the open C2PA standard backed by Adobe, Microsoft, and LinkedIn, among others; on:mint extends the standard with a cryptographic hash, watermark, perceptual fingerprint, deepfake detection, and an immutable anchor, so the label stays provable even after the file has been edited or re-compressed. That restores transparency and gives digital assets a clear quality signal again. It becomes visible via the Cr icon: one click shows the full provenance history.
We convert them: existing metadata is transferred into the C2PA format, and entire holdings can be signed and verified in batch.
Three ways: the web app for single files with no developer effort, the API for batch processing and production pipelines with usage metering, and MCP for integration into agent workflows.
Our verdict is honest: if content isn't verifiably AI, we don't label it as AI. That also protects your genuine originals from false suspicion.
The infrastructure is located in the EU. Anyone can read the credentials – that is the point of an open standard. You control which details become public: sensitive metadata such as exact GPS locations does not have to be published. Only authorized parties can create and sign credentials; on:mint signs as a C2PA issuer.
