Does the EU AI Act Require You to Label AI-Translated Content?

If you run a website in more than one language, the headlines about the EU AI Act can leave you wondering whether your translated pages now need a visible AI label. The short answer is usually: “No”. However, the confusion is understandable given how much the guidance has changed over the past few months.

This post is general information about how the EU AI Act’s transparency rules affect AI-translated websites. It is not legal advice, and it does not create a lawyer-client relationship. For guidance on your specific situation, consult a qualified professional.

This page walks through what Article 50 of the AI Act asks for and what’s changed in the Commission’s final Guidelines. Also, we’ll look at how Weglot already gives you the visibility the law is aimed at.

Key Takeaways

• Most commercial translations don’t need visible disclosure. Article 50(4) only covers AI-generated text published to inform the public on matters of public interest. This excludes typical marketing, product, and support content.
• AI translation no longer triggers the machine-readable marking duty. The Commission’s final Guidelines move AI-generated translation into a ‘standard’ editing category.
• Weglot already tags every translation by how it was produced. Labels give you an owner-facing audit trail no matter what visitor-facing disclosure you choose.

What the EU AI Act’s Article 50 Actually Covers

Regulation (EU) 2024/1689 (we’ll refer to it simply as the ‘AI Act’), sets out its transparency rules in Article 50. These apply in 4 distinct situations:

• AI systems that interact directly with people (such as chatbots) need to make that fact clear unless it is already obvious.
• AI systems generating synthetic audio, image, video, or text need machine-readable marking so the output is detectable as artificially produced.
• Emotion recognition and biometric categorization systems require deployers to inform the people exposed to them.
• Deep fakes and AI-generated text published on matters of public interest need a disclosure that the content is artificially generated or manipulated.

You might see the second and fourth situations and worry that a translated page of any description might need a visible disclaimer. It’s confusing, but we can clear it up.

Why Most AI-Translated Websites Don’t Need a Visible AI Label

The European Commission adopted its final Guidelines on Article 50 less than two weeks before the rules took effect. Of these, one change matters more than any other for translated sites.

What Changed in the Final Guidelines

Earlier drafts grouped AI-generated translation with summaries and other substantive rewrites. This would have meant you’d have been obligated to declare machine-readable tags on your AI-generated content.

However, the final guidelines reversed that. AI-generated translations now sit in the standard editing examples instead, alongside grammar correction and spellchecking. There are a few takeaways to note:

• Translation is exempt from Article 50(2) since it doesn’t change the substance or meaning of the underlying text.
• Summaries and substantive rewrites remain in scope, so the exemption is specific to translation. It doesn’t extend to AI systems that condense or rework content in the same language.
• The reversal is a recent change (projected to be in August 2026), so anything you read about Article 50 and translation published before that date may still describe the earlier, stricter draft position.

While there’s a separate rule that covers visible disclosure (Article 50(4)), it was never really aimed at commercial translation. 2 conditions both need to be true before it applies to a piece of text:

• The text is AI-generated or AI-manipulated, and
• It’s published with the purpose of informing the public on a matter of public interest: journalism and political commentary, for example.

Even where both conditions are met, it still doesn’t apply where the content has gone through human review or editorial control and someone (or something) named holds editorial responsibility for it.

So, a translated ecommerce store, a SaaS marketing site, a product catalog, or a support center does not fall into the public interest category to begin with. In contrast, a translated blog covering current affairs or policy is closer to the kind of content the rule was written for.

Even so, you can still choose to disclose if you wish. You might want to display an AI translation notice to build trust with visitors, even where it’s not required. Regardless of your choice, Weglot can support it either way.

How Weglot Already Tracks AI-Refined and Human-Edited Translations

The AI Act treats transparency towards both you and your visitors differently. Weglot can help with both of these scenarios.

Inside your dashboard, every translation carries a tag showing exactly how it was produced:

• Automatic Translation marks text generated by Weglot’s first-layer automatic translation, drawn from providers including DeepL, Google Translate, and Microsoft.
• GenAI marks translations refined through Weglot’s AI Translation Model, which adjusts tone, phrasing, or brand consistency beyond the base translation.
• Manual Translation marks anything you edit directly inside the Translation List, overriding either of the automated layers.

As such, you are never left guessing at whether content is a direct automatic (or AI) translation and which has had a human review. It means you can filter your entire Translation List by any of these tags at any time.

How to Add an Optional AI Translation Notice to Your Site

If you decide you want visitor-facing disclosure, whether for a public-interest page or simply as a trust signal, turning it on takes a few minutes.

‍

In fact, there are only 2 steps to take, starting after you open your project from the Weglot Dashboard. First, head to Settings > General, turn on the AI translation notice, then click Save Changes in the top right-hand corner. Then, point it at a location on your page.

Weglot shows the message on the translated versions of your site. This notice covers typical cases, but if you have pages that see closer scrutiny or sit closer to the public interest, you’ll want something more visible than a small footer line.

A simple and prominent disclaimer, such as “Part of this website was translated with AI provided by Weglot” can be placed in almost any on-site location:

• In the body of the page itself, near the content it describes, for maximum visibility.
• In your site footer, so it applies site-wide without repeating on every page.
• Alongside a byline or publication date, if the translated content is editorial in nature.

The AI Act doesn’t state any required wording either, so you can phrase the notification in any way that satisfies the intent behind Article 50.

Does a Human Review Change Your Compliance Position?

Manual and human reviews do change compliance, but with some complications. Having a person review and approve a translation triggers the Article 50(4) exception for public-interest text.

However, this will play out differently depending on the article in question:

• For Article 50(4) disclosure, human review with editorial responsibility is the exception itself. Without it, public-interest text generated or manipulated by AI needs a visible disclosure.
• For Article 50(2) marking, translation is classed as standard editing regardless of any other human review.

Since AI-generated translations are standard editing, generative content (such as AI images or synthetic audio) doesn’t apply to translated text. Editing a translation is still good practice for quality and brand voice though. However, this does unlock an exception on the rare page where it counts.

In a nutshell, businesses relying on Weglot do not need a review step purely to satisfy Article 50(2) of the AI Act.

What This Means for Businesses Translating With Weglot

We admit, the AI Act can be confusing for multilingual website translations. If you run a marketing site, an online store, a SaaS product, or almost any commercial website that happens to publish in more than one language, you’ll likely be okay. The AI Act’s transparency rules were written with a narrower target in mind, such as synthetic media, deep fakes, and content shaping public debate.

While non-compliance with Article 50 can carry heavy fines similar to GDPR issues, it’s important to understand whether this really applies to you:

• Your translations are not subject to Article 50(2) since AI-generated translations are classed as standard editing.
• Your translated pages are unlikely to trigger Article 50(4) unless they specifically inform the public on a matter of public interest.
• You already have the owner-facing visibility the Act is concerned with through the Automatic Translation, GenAI, and Manual Translation tags in your dashboard.

The elements of what the act does ask of you is already built into how Weglot works. For instance, you can see automatic translations, those with AI refinement, and manual reviews. If you simply want an extra layer of trust, you can use a footer notice or more visible custom disclaimer.

Getting your multilingual site right involves more than a single legal question and most of the groundwork is already covered by Weglot.
