The AI Disclosure Line (EU AI Act)

September 5, 2026 4 min read

What it does: Adds one sentence at the very bottom of every article Antradus wrote — "This content was created with the help of AI (Antradus AI – gpt-4o)." — naming the model that actually wrote it. On by default, in every edition.

Applies to Antradus AI Lite, Publisher & Studio v2.9.0 · Last updated 2026-08-30

The EU AI Act, Article 50, asks anyone who publishes AI-generated text to make it clear to readers that it is AI-generated. This is that line. It is switched on out of the box, and it costs you nothing to leave on.

What readers see

At the end of the article, below everything else on the page:

This content was created with the help of AI (Antradus AI – gpt-4o).

Smaller and quieter than body text, but never hidden. It appears on the published page and in your RSS feed.

Where the setting lives

Antradus AI → Settings → AI Disclosure.

Setting What it does
Show the disclosure On by default. Turn it off and the line disappears from every article at once.
Wording The sentence itself. [model] becomes the model that wrote the article; [provider] becomes the company behind it — OpenAI, Anthropic, Google Gemini, OpenRouter or DeepSeek. Emptying the box restores the default sentence.

The screen shows you how the line will read on something written right now, so you never have to publish a post to check your wording.

Which posts get it

Only the ones Antradus wrote:

  • an article written in the editor with Start Writing,
  • an article published by Bulk Publishing, including SEO clusters, Google Trends and podcast spin-offs,
  • a WooCommerce product description written from a photo.

Posts you wrote yourself are never touched. Neither are posts you only edited with the AI Assistant, the highlight-text tools or Human Voice — using AI to tighten a paragraph you wrote is not the same as AI writing the article, and the line should say only what is true.

A CSV import is never marked either: that text came from you, not from a model.

The line names the model that actually wrote the article

The model is recorded on the post at the moment it is written. Switch your provider to Claude next month and last month’s articles keep saying gpt-4o, because that is what wrote them.

Turning it off for one post

If you rewrote an article by hand until nothing of the AI draft is left, open it in the editor and untick Show the AI disclosure on this post in the AI Disclosure box. That post stops showing the line; every other one is unaffected.

The box only appears on posts Antradus wrote — there is nothing to decide on the others.

Switching it on later

The provenance is recorded whether the disclosure is on or off. So if you turn it on a year from now, everything written since this version is covered immediately — not just what you write next.

Articles written before this version have no record of which model wrote them, so they show nothing. If you want them covered, open one and re-generate it, or set the model yourself:

// Mark an older post as AI-written, naming the model that wrote it.
update_post_meta( 123, '_antradus_ai_model', 'gpt-4o' );
update_post_meta( 123, '_antradus_ai_provider', 'openai' );

For developers

Three filters, all in includes/disclosure.php:

// Style it yourself, or move it inside your own wrapper.
add_filter( 'antradus_ai_disclosure_html', function ( $html, $post_id, $sentence ) {
    return '<aside class="my-ai-note">' . esc_html( $sentence ) . '</aside>';
}, 10, 3 );

// Keep it off one post type entirely.
add_filter( 'antradus_ai_disclosure_show', function ( $show, $post_id ) {
    return 'product' === get_post_type( $post_id ) ? false : $show;
}, 10, 2 );

The sentence is never written into the post content — it is added when the page is read. That is deliberate: it means changing the wording updates every article at once, and nobody can delete the disclosure by accident while rearranging paragraphs.

This is not legal advice

The line is here so the plain case is handled properly out of the box. Whether your publication needs more than a sentence — an author byline policy, an editorial note, a disclosure page — is a question for you and your lawyer, not for a plugin.
