The EU AI Act and human review of AI-written text

Under the EU AI Act, you must say when AI wrote or changed text you publish to inform the public about matters of public interest. You don’t have to if someone who knows the subject has checked it, facts included, and someone takes editorial responsibility.

What does Article 50(4) of the EU AI Act say?

Deployers of an AI system that generates or manipulates text which is published with the purpose of informing the public on matters of public interest shall disclose that the text has been artificially generated or manipulated. This obligation shall not apply where the use is authorised by law to detect, prevent, investigate or prosecute criminal offences or where the AI-generated content has undergone a process of human review or editorial control and where a natural or legal person holds editorial responsibility for the publication of the content.

Regulation (EU) 2024/1689, Article 50(4), second subparagraph. Read the full text on EUR-Lex.
  • The law applies to you if you use AI to write or change text that you publish to inform the public about matters of public interest.
  • If it applies to you, you must say that the text was generated or changed by AI.
  • You don’t have to say the text was generated by AI if a person has reviewed it or it has been through editorial control, and a person or organization takes editorial responsibility for publishing it.

The European Commission’s guidance adds that the review has to look at what the text says, including whether the facts are right. A spelling or grammar check on its own is not enough. Read the guidance.

Is this rule in force now?

Yes. This rule is in force now, and it has been since August 2, 2026.

What does “matters of public interest” mean?

The AI Act does not define the phrase. The European Commission explains it in its guidance on Article 50. It says matters of public interest are topics that matter to society at large, whether locally, nationally, across the EU or worldwide, and that deserve public debate or scrutiny.

The guidance names politics and elections, public administration and public services, the courts and law enforcement, fundamental rights, public security, public health, the environment and consumer safety. It also names any economic, financial, political, scientific or cultural development that people may debate in public. It says what counts can change over time and from one place to another.

It gives examples the law covers: an AI summary of a news story about a town council decision, a lifestyle article that compares diets for a disease, a public company’s reports for investors, and a weather service’s post warning people about a storm.

It also gives examples the law does not cover: fantasy novels, ads and product descriptions that make no claims about health, consumer safety or sustainability, a news summary that a chatbot shows only to the person who asked for it, and a consultant’s advice to a client. Private emails and a company’s internal messages are outside the rule too, because they are not published.

How can a Proofed editor help?

A review costs $60 per 1,000 words. You pay for the exact number of words.

All Proofed editors are highly trained. They read your text and the AI’s changes, and they use their own judgment. They catch what the AI missed or got wrong, and they check that the meaning is right. Then they send you a final file.

You keep the editor’s file and the date they finished it. That is your record that a person reviewed the text before you published it.

So before you publish, a person has reviewed your text, not only a machine. You still decide what to publish, and you or your organization keep editorial responsibility for it.

Who should think about this?

You run a news site and use AI to draft stories. News is about matters of public interest, so the law applies to you. You can label each story as AI-written. Or you can have a person review it before it goes out, and you or your company take editorial responsibility for it.

Your company’s shares trade on a stock exchange, and you use AI to help write the reports you post for investors. The Commission’s guidance uses this very case as an example the law covers. Have a person review each report before you post it, or say that AI helped write it.

You write health articles for a lifestyle blog and use AI to tidy them up. Health is a matter of public interest, even on a lifestyle site. The guidance gives an article comparing diets for a disease as an example.

You use AI to write the product descriptions in your online store. The guidance says product descriptions are usually outside this rule. That changes if they make claims about health, safety or sustainability.

Does it cover all AI-written text?

No. This part is about text published to inform the public on matters of public interest. Other parts of Article 50 are about things like chatbots, deepfakes and AI-made images.

Can a Proofed editor take editorial responsibility for my text?

No. Our editor reviews the text, but you or your organization keep editorial responsibility for what you publish.

What record do I get of the review?

You get the editor’s file on your document page. Through our API, you also get the date the editor sent it back, their deadline and the word count.

How much does the review cost?

A Proofed editor reviews your document for $60 per 1,000 words. You pay for the exact number of words, so a 3,420-word report costs $205.20. The AI proofread costs 1 token for every 1,000 words on top.
