EU AI Act vs GDPR: What's the Difference and What Does Your Website Need?
Many website owners are already familiar with the GDPR — the privacy regulation that reshaped how websites handle personal data since 2018. Now the EU AI Act adds another layer of EU regulation. But these two laws cover fundamentally different things. This article explains the key differences, where they overlap, and what your website needs for each.
One-line difference: GDPR is about data protection (how you collect, store, and use personal data). The EU AI Act is about AI transparency and safety (how you use and disclose AI systems to users). An AI chatbot can create obligations under both — but for different reasons.
What GDPR covers
The General Data Protection Regulation (EU 2016/679) applies whenever you process personal data of people in the EU. Its core requirements for websites include:
- A privacy policy explaining what data you collect and why
- Cookie consent for non-essential cookies
- A legal basis for processing data (consent, legitimate interest, contract, etc.)
- The right of users to access, correct, or delete their data
- Data processing agreements with third-party services
GDPR is enforced by national Data Protection Authorities (DPAs) in each EU member state. Fines can reach €20 million or 4% of global annual turnover.
What the EU AI Act covers
The EU AI Act (Regulation 2024/1689) applies when you deploy AI systems that interact with users. For most small business websites, the relevant provision is Article 50, which requires:
- A disclosure before or at the start of any AI chatbot conversation
- Labelling of AI-generated text when it informs the public about matters of general interest
- Disclosure of deepfake imagery (synthetic realistic representations of real people)
The AI Act is enforced by national AI market surveillance authorities. The transparency obligation deadline is August 2, 2026.
Side-by-side comparison
| Aspect | GDPR | EU AI Act (Art. 50) |
|---|---|---|
| Topic | Personal data protection | AI transparency & safety |
| In force since | May 2018 | August 2026 (Art. 50) |
| Trigger | Processing personal data of EU residents | Using AI systems facing EU users |
| What users get | Rights over their data | Disclosure that they're interacting with AI |
| Core document | Privacy policy + cookie notice | AI transparency statement + chatbot disclosure |
| Max fine | €20M or 4% global turnover | €15M or 3% global turnover (Art. 50 violations) |
| Enforced by | National DPAs (e.g. ICO, CNIL, AP) | National AI authorities |
Where they overlap: AI chatbots
An AI chatbot is the most common point where GDPR and the AI Act both apply to the same feature:
- Under GDPR: if the chatbot collects personal data (names, email, health queries), you need a legal basis, a privacy notice, and likely a data processing agreement with the chatbot vendor
- Under the AI Act: you must disclose to users that they are talking to an AI, before or at the start of the conversation
These are separate obligations that reinforce each other. A chatbot disclosure ("You're chatting with an AI") does not satisfy GDPR data collection requirements, and a privacy policy does not satisfy the AI Act chatbot disclosure requirement.
GDPR already required you to do some of this
If your chatbot collects data, GDPR's transparency principle (Article 5(1)(a)) already required you to be clear about how that data is used. The AI Act adds a specifically worded obligation about AI identity — which is a narrower, more concrete requirement than GDPR's general transparency principle.
In practice: if you have a GDPR-compliant privacy policy and cookie notice, you are not starting from scratch for AI Act compliance. The chatbot disclosure and an AI transparency statement are typically the two additional steps required.
Practical checklist: covering both
- Privacy policy mentioning AI use (chatbot, AI-generated content) — satisfies GDPR transparency and AI Act good practice
- Cookie consent for chatbot analytics or tracking cookies — GDPR requirement
- Data processing agreement with your chatbot vendor — GDPR requirement
- Chatbot opening message disclosing AI interaction — AI Act requirement (new, Aug 2026)
- Standalone AI transparency statement page — AI Act best practice; good supplement to privacy policy
Do not confuse the two
A common mistake: updating the privacy policy to mention AI and assuming that covers the AI Act. It does not. The AI Act's chatbot disclosure obligation is about informing users in the moment, in the chat interface, before they start interacting — not in a legal document few people read. Similarly, an AI disclosure notice does not replace your GDPR privacy policy.
Both frameworks require their own dedicated steps. The good news: those steps are small, and after years of GDPR implementation most businesses already have the right instincts for documentation and transparency.
