Labeling AI Text: What Really Applies to ChatGPT Content

Updated: July 21, 2026

Do you have to label AI text as soon as you use ChatGPT, Gemini, or Claude for your website, your blog, or your product descriptions? Hardly any question causes more uncertainty right now, and more half knowledge. The short answer up front: no, not every text created or edited with AI has to be disclosed. The AI Act ties the text obligation to narrowly defined conditions that do not cover a large share of everyday content production at all. This article explains precisely when labeling actually applies to text, when the exemption for editorial control relieves you of it, what applies to chatbots, and where the most common misconceptions lie.

The legal basis is Article 50 of the AI Act, whose transparency obligations apply from August 2, 2026. Our guide to the AI labeling requirement under the EU AI Act provides a full overview.

Key Takeaways

• No automatism: using ChatGPT alone does not trigger a labeling requirement for your text.
• Two roles, two obligations: the machine readable marking (Art. 50(2)) applies to the provider (e.g. OpenAI), not to you. The visible disclosure (Art. 50(4)) applies to you as the deployer.
• Narrow scope: the deployer's text obligation only applies to texts on matters of public interest, not to product, marketing, or service texts.
• Editorial exemption: if you review the text editorially and take responsibility for it, the obligation does not apply even for topics of public interest.
• Chatbots are separate: anyone who chats directly with people must disclose at the start that it is an AI, this obligation is not postponed.
• From August 2, 2026 the obligations apply; fines of up to 15 million euros or 3 % of global annual turnover are possible for violations.

Two completely different obligations, and who they affect

The most common misconception about AI text: people lump the obligations of AI providers and AI users together. Article 50, however, clearly distinguishes between two roles. Which role you occupy determines your obligations, details in the article on provider and deployer obligations.

Provider (Art. 50(2)): the machine readable marking

The provider is whoever develops and offers the AI system, for generated text that means, for example, OpenAI with ChatGPT or Google with Gemini. Under Article 50(2), the provider must mark synthetic text outputs in a machine readable format and make them recognizable as artificially generated. According to the regulation, the solutions must be "effective, interoperable, robust and reliable," "as far as this is technically feasible." In practice, that means watermarks, metadata standards, or cryptographic provenance proofs like C2PA.

Important for you: this obligation does not apply to you as a user. You do not have to build invisible watermarks into your texts. The provider of the language model is responsible.

Deployer (Art. 50(4)): the visible disclosure

The deployer is whoever uses the AI system, meaning you, when you generate and publish text with ChatGPT. This is where the key point lies that resolves most misunderstandings: the disclosure requirement for AI text under paragraph 4 applies only to texts that are published to inform the public about matters of public interest. For art and satire, the regulation also provides for a lighter standard that does not impair artistic freedom.

The role logic at a glance:

When you must label AI text, and when not

This is the central message for everyone who wants or needs to label ChatGPT text on their website: the deployer's text obligation targets a specific slice, content in the journalistic informational space on topics of public interest (for example reporting on politics, society, health, the judiciary, or current events).

The following overview shows which content is typically covered and which is not:

So if you write a blog article about the best hiking boots or a product page with ChatGPT, this use alone does not, under the current state of the law, trigger a legal labeling requirement for the text under Article 50. That relieves a large share of everyday content production, especially in e commerce and marketing.

Note: other areas of law remain unaffected. Competition law, press law, or copyright law can create their own transparency requirements in individual cases. A cease and desist letter is also conceivable if consumers are deceived, more on this in the article on fines and warning letters. The AI Act is only one building block.

The exemption: editorial control

Even for texts on matters of public interest, the obligation does not apply automatically. Article 50(4) contains an explicit exemption for editorial control: the disclosure obligation does not apply if the AI generated content has undergone human review or editorial control and a natural or legal person bears editorial responsibility for the publication.

In plain terms: if you review a draft from AI for content, revise it, take factual responsibility for it, and publish it under your editorial responsibility, you do not have to label it as AI text. The legislator thereby recognizes that a carefully edited text is no longer a mere, unchecked machine product. This editorial control exemption for AI text is the most important relief point for editorial teams and content teams.

That does not mean that "reading it over once" is enough. What is meant is genuine substantive control with clear acceptance of responsibility, not the unchecked copy paste of a prompt. Here is how you recognize genuine editorial control:

• Content review: facts, figures, and sources are checked and corrected.
• Substantial editing: the text is adapted structurally and linguistically to your standards, not just cosmetically.
• Named responsibility: a person or organization stands as editorially responsible for the publication.
• Documentation: the approval process is traceable, for example through an editorial or approval workflow.

Whoever documents taking on this responsibility is well positioned in a dispute. You will find a structured template for this in our AI labeling checklist.

Edge cases from practice

Theory is clearer than everyday practice. Four scenarios that regularly spark discussion in practice:

Scenario 1, the AI health guide without editorial oversight. A portal automatically generates articles on symptoms and treatments and publishes them without expert review. Health is a matter of public interest, editorial control is missing, so the labeling requirement applies here. The notice belongs visibly on the article.

Scenario 2, the revised press release. You have ChatGPT write you a draft for a release on a socially relevant topic, check every statement, add quotes, and approve it under your name. The editorial exemption applies, AI labeling is not required under Art. 50.

Scenario 3, the AI product description in the shop. You generate 500 product texts for your online shop. Product descriptions serve sales, not informing the public about matters of public interest. The text obligation under Art. 50(4) does not apply, though you should still think about AI product images, which trigger their own requirements on Amazon and eBay, for example.

Scenario 4, the manipulated article with an AI image. As soon as a realistic AI image or video comes into play that deceptively depicts a person or event, the stricter deepfake rules apply, regardless of whether the accompanying text requires labeling.

Chatbots: a separate disclosure obligation applies here

The situation is different for chatbots and AI assistants that interact directly with people. For AI systems intended to interact with natural persons, Article 50 requires that the people affected be informed that they are dealing with an AI system, and this must happen at the start of the interaction.

So if you are labeling a chatbot as AI, a clear notice belongs at the start of the conversation, for example: "You are chatting with an AI assistant." This obligation only ceases to apply if it is obvious to a reasonably informed user from the circumstances anyway. When in doubt, disclose transparently. Unlike the postponed machine readable marking for legacy systems, the chatbot disclosure is not postponed and is relevant from August 2, 2026.

How to correctly label an AI text

If your text falls into the labeling required area (public interest, no editorial control), a clear, clearly visible notice directly on the content is enough. Here is how to proceed:

1. Choose the location: place the notice where the user perceives the content, at the beginning or directly below the piece, not hidden in the footer or legal notice.
2. Choose the wording: a simple, understandable sentence is enough, for example: "This article was created with the support of artificial intelligence."
3. Optionally add the EU icon. The EU icons for AI content provided by the EU Commission (in the variants "basic," "fully AI generated," and "partially AI modified," each as SVG and PNG) are an optional, not a mandatory, tool, but they increase recognizability.
4. Document it: keep a record of which content you labeled and how, this makes proof easier if it comes to that.

A single sentence in the legal notice or way down in the footer is usually not enough, the notice belongs where the user actually sees the content.

Practical tip: the real effort usually does not lie with text but with images and videos, for which a visible label plus machine readable metadata is required far more often. That is exactly what our free AI labeling tool is for: it places the official EU label on images and videos, writes machine readable metadata (IPTC DigitalSourceType/XMP, optionally C2PA), generates proof with a SHA-256 checksum and timestamp on request, and processes entire batches. For pure text content, the visible sentence notice described above is sufficient in practice.

Checklist: do I need labeling?

Work through these five questions in order:

• Is the content text (not an image/video)? If no, check the separate image/video rules.
• Does the text inform the public about a matter of public interest? If no, no text obligation under Art. 50(4).
• Is genuine editorial control with acceptance of responsibility missing? If such control takes place, the exemption applies, no obligation.
• Is it art or satire? If yes, a lighter standard applies, artistic freedom is preserved.
• Is it a chatbot? If yes, a notice is always required at the start of the interaction.

If open questions remain after this review, the AI labeling glossary helps with the terminology.

Deadlines and fines

The transparency obligations under Article 50 apply from August 2, 2026 (24 months after the AI Act entered into force on August 1, 2024). You should know two points:

• The core deadline remains August 2, 2026. The visible deployer disclosure (paragraph 4) and the chatbot labeling are binding from this date.
• Partial postponement through the Digital Omnibus. Under the provisional status (Digital Omnibus, May 2026), the machine readable marking (paragraph 2) for systems already placed on the market before August 2, 2026 is postponed to December 2, 2026. Visible labeling by deployers is not affected by this.

Violations of the transparency obligations carry fines of up to 15 million euros or 3 % of global annual turnover (whichever amount is higher). You will find a breakdown of all dates and sanctions under AI Act deadlines and fines.

Frequently asked questions (FAQ)

Do I have to label ChatGPT text on my website?

In most cases, no. The labeling requirement for AI text under Article 50(4) only applies to content published to inform the public about matters of public interest. Normal product, marketing, or guide texts usually do not fall under it.

Do I have to label AI text if I revise it myself?

No, if genuine editorial control takes place. The regulation explicitly exempts content that has undergone human review and for whose publication a person bears editorial responsibility. What is meant is a substantive review with acceptance of responsibility, not merely skimming it.

What must be labeled with AI text, and what does not?

AI generated texts on matters of public interest without editorial control require labeling. Typically not covered are product descriptions, advertising texts, newsletters, and service texts, as well as all content that you edit and take editorial responsibility for.

Do I have to label a chatbot as AI?

Yes. AI systems that interact directly with people must inform users at the start of the interaction that they are communicating with an AI, unless that is obvious. A short notice like "You are chatting with an AI assistant" fulfills this obligation.

Who is responsible for AI text, me or OpenAI?

Both, but for different obligations. OpenAI, as the provider, is responsible for the machine readable marking of the output (Art. 50(2)). You, as the deployer, are responsible for the visible disclosure, if the text falls into the labeling required area (Art. 50(4)).

Does the obligation also apply to automatically generated news?

Yes, if it concerns matters of public interest and is published without editorial control. Fully automatically generated news items without human approval are a typical application case of the labeling requirement.

Is a notice in the legal notice enough?

Usually not. The notice must be clear and visible where the user perceives the content, meaning at or immediately next to the article, not exclusively in the legal notice or footer.

From when does the labeling requirement for AI text apply?

The transparency obligations under Article 50 apply from August 2, 2026. The machine readable marking by providers for systems already placed on the market before this date was provisionally postponed (Digital Omnibus, May 2026) to December 2, 2026; the visible disclosure by deployers and the chatbot labeling are not affected by this.

What happens in case of a violation?

For violations of the transparency obligations under Article 50, the AI Act provides for fines of up to 15 million euros or 3 % of global annual turnover (whichever amount is higher).
