EU AI Act vs GDPR: What's the Same, What's New, and What Your Website Still Needs

If you already have a GDPR-compliant website — a privacy policy, a cookie consent banner, the right data processing agreements — you might reasonably assume you've handled the main EU digital compliance obligations. For most of the past six years, you were right. From 2 August 2026, that assumption has a gap in it.

EU AI Act Article 50 creates a new transparency obligation that your existing GDPR setup doesn't cover. Understanding the difference is worth five minutes of your time before the deadline arrives.

What GDPR and Article 50 have in common

Both are EU regulations with real teeth. Both apply to businesses outside the EU if they serve EU users. Both require you to be transparent with the people who interact with your website. Both can result in significant fines for non-compliance.

That's where the overlap ends.

What GDPR covers — and what it doesn't

GDPR is about personal data. It governs how you collect it, store it, process it, and allow people to control it. When you added a cookie banner to your site, you were telling visitors: "we use cookies that track your behaviour, here's what they do, here's your choice." When you published a privacy policy, you were documenting what personal data you collect and why.

GDPR says nothing about whether your chatbot is human or AI. It has no requirement to tell visitors they are talking to an automated system. That obligation doesn't exist in GDPR — it exists in the EU AI Act.

What Article 50 actually requires

Article 50(1) of the EU AI Act states that deployers of AI systems designed to interact directly with people must ensure those people are informed they are interacting with an AI system — at the latest at the start of the first interaction.

This means: if your website has a chatbot, a live chat with AI-suggested replies, or any AI assistant that responds to visitors in real time, you need a clear disclosure. Not buried in your privacy policy. Not in the footer. In the conversation itself, before the visitor types anything.

The obligation has nothing to do with cookies, tracking, or data processing. It's about something simpler: being honest that your visitor is talking to a machine.

The two setups your website needs

Think of it as two parallel compliance layers, each addressing a different question:

Your GDPR setup answers: "What data do we collect about you, and what are your rights?"

Your Article 50 setup answers: "Are you currently talking to a human or an AI?"

A cookie banner doesn't answer the second question. A privacy policy doesn't answer it either. Even a well-drafted AI clause in your privacy policy doesn't satisfy Article 50 — because the obligation is about real-time disclosure at the moment of interaction, not a policy document someone reads before visiting your site.

The evidence requirement — where the gap becomes expensive

Here's the part most businesses miss. Article 50 doesn't just require a disclosure — it requires you to be able to prove the disclosure was shown, on a specific date, in a specific form, to users interacting with your system.

A screenshot of your chatbot today doesn't prove it was there in September. Your chatbot's current settings don't prove what was shown three months ago when a regulator asks. This is a different compliance burden than GDPR — GDPR requires consent records, and most cookie solutions handle that automatically. Article 50 requires disclosure event records, and almost nothing handles that automatically yet.

What to do before 2 August 2026

Three steps, in order:

1. Check whether Article 50 applies to your setup — not every website is in scope. The obligation covers AI systems that directly interact with visitors. An AI writing tool you use internally doesn't count. A chatbot your visitors type messages to does.
2. Add a first-interaction disclosure to every in-scope AI touchpoint — specific wording that appears before the visitor can send their first message, in a form that's clearly noticeable.
3. Keep a continuous record that the disclosure was shown — not a one-time screenshot, but an ongoing log tied to actual display events, with timestamps.

Get the disclosure and the evidence log in one step

The Disclo Compliance Kit includes ready-made disclosure texts for chatbots, voice agents, and AI-content pages — in your language, based on official EU guidelines, ready to copy and paste. The Disclo Pro badge adds automatic evidence logging: every time the disclosure fires, it's timestamped and stored on your account, exportable on demand.

This is general guidance, not legal advice. Based on the official EU AI Act and the Article 50 draft guidelines published 8 May 2026.
