What Article 50 of the EU AI Act Asks of a WordPress Chatbot

If you use an AI chatbot on your WordPress or WooCommerce site to answer customer questions, one specific rule now applies to it. The EU AI Act — Regulation (EU) 2024/1689 — entered into force in August 2024 and applies in stages; Article 50, the transparency article, has applied since 2 August 2026.

In this post, we'll cover what this means for your site and how you can implement a technically sound solution.

What is Article 50 of the EU AI Act?

Article 50(1) is addressed to providers: they must design and develop AI systems intended to interact directly with natural persons so that those persons are informed they are interacting with an AI system — unless that is already obvious to a reasonably well-informed, observant and circumspect person. Article 50(5) adds the timing: the information must be given clearly and distinguishably at the latest at the time of the first interaction, and must conform to the applicable accessibility requirements.

That duty sits on the provider of the system rather than on you as the site owner — though you can become a provider yourself under Article 25 if you put your own name or trademark on a system, or modify it substantially. In practice the disclosure has to appear on your site, so the question that matters to you is whether the plugin you installed makes it. For a longer look at the detail, see our Article 50 case study.

How Our Chatbot Handles Compliance

We designed the AI Customer Support Chatbot & Lead Automator with this exact requirement built-in from day one. It is active by default.

Here is how we meet the technical transparency requirements:

  1. Visual Disclosure: The widget explicitly states it is an AI at the top of the chat panel.
  2. Accessibility Disclosure: The accessible name of the button that opens the chat includes the AI disclosure, ensuring screen reader users are also informed immediately.

Honest Limits: What You Need to Know

While our plugin handles the transparency requirement effortlessly, it's important to be honest about the limits of automation.

Prompt Injection: No prompt-level measure fully solves prompt injection. We isolate retrieved passages into a block and instruct the model to treat them as untrusted data. However, the real boundary is who may publish on your site. Since the bot indexes your published pages, posts, and WooCommerce products, an Author or Shop Manager could theoretically plant instructions that change what the bot tells visitors. Control your user roles carefully.

Data Privacy: Visitor messages leave your site and go to the AI provider you configure (like Google Gemini, OpenAI, or Anthropic). However, visitor names, emails, and anything typed into the human lead form stay strictly on your WordPress database.

And a disclosure is one obligation, not the whole regulation. Getting the notice right settles Article 50 for a chat widget. It does not make you compliant with the AI Act, which reaches further than transparency and lands differently depending on the role you occupy, what your system actually does, and how your member state enforces it. This plugin is a tool: it handles one requirement properly and it cannot see your situation. If your exposure is real, a plugin is not the thing to ask.

No Per-Message Fees

Many AI plugins charge you a monthly subscription based on the number of messages your visitors send. We don't. You bring your own API key (for example, Google Gemini's free tier covers most small sites without any license required for the base functionality), and your key is stored with authenticated AES-256 encryption.

What to Check on Your Own Widget

You do not need a compliance audit to open your own chat widget and see whether it says what it is. Ours ships with that disclosure switched on, and you can install it on WooCommerce or WordPress in less than two minutes.

FAQ

Does the AI Act apply to me if my business is outside the EU? Article 2 reaches providers and deployers established outside the Union where the output of the system is used in the Union, so sitting outside the EU does not by itself put you outside the regulation. Whether it catches your particular setup depends on facts about your business that a blog post cannot know, and that one is worth asking a lawyer.

Can I customize the bot to hide the AI disclosure? Yes. There is a switch in the settings, and a filter for developers, because Article 50(1) does not require the disclosure where it is already obvious to a reasonably well-informed, observant and circumspect person. We ship it switched on, and the settings screen warns you when you turn it off, because whether your widget is obvious enough is your judgement and your risk — Article 99(4) puts non-compliance with Article 50 in the band reaching €15 million or 3% of worldwide turnover. We would rather give you the switch and the warning than pretend the exception does not exist.

Does the bot hallucinate answers? The plugin indexes your specific published content (titles, text, prices, stock) and is instructed to answer only from that content rather than its general knowledge. If it doesn't know the answer, it offers to fetch a human and captures the lead.
