AI chatbots deployed in Germany are subject to Article 50 of the EU AI Act and GDPR. Article 50 requires clear, upfront disclosure that users are interacting with an AI — this obligation applies from August 2, 2026. GDPR applies in parallel whenever the chatbot processes personal data. Employee-facing chatbots additionally require works council approval under §87 BetrVG before deployment.

Transparency Is the Core Requirement

Article 50 of the AI Act requires one thing: people must know they’re talking to AI, not a human. This applies unless it’s already obvious from context.

In practice, this means clear disclosure at the start of every conversation. “Hi, I’m an AI assistant”—something like that. Don’t bury it in terms of service nobody reads.

GDPR Adds Another Layer

Your chatbot processes personal data the moment someone types their name or email. That triggers GDPR requirements: legal basis for processing, privacy notice updates, data minimization, retention limits.

Most chatbots can rely on legitimate interest as a legal basis. But document your reasoning and make sure your privacy policy mentions AI processing.

Works Councils Matter in Germany

If your chatbot interacts with employees—internal help desk, HR questions, IT support—the Betriebsrat has co-determination rights under §87 BetrVG. This isn’t optional. You need their approval before deployment.

Using employee conversations to train your chatbot? That requires explicit consent, not just works council agreement.

What This Means Practically

For most companies, chatbot compliance is straightforward: add clear AI disclosure, update your privacy policy, and involve the works council for employee-facing bots. The August 2025 transparency deadline and August 2026 high-risk deadline are approaching. For further reading, see our guides on AI customer service compliance and AI natural language processing.

How Compound Law Helps

• AI disclosure language that meets regulatory expectations
• GDPR-compliant privacy policy updates
• Works council negotiation for employee chatbots
• Ongoing compliance monitoring

Frequently Asked Questions

Is my chatbot high-risk? Almost certainly not. Chatbots are classified as limited risk unless they make consequential decisions about people.

What if it’s obvious it’s a bot? The AI Act has an exception for obvious AI. But “obvious” is legally uncertain—explicit disclosure is safer.

Do internal chatbots need works council approval? If they interact with employees or process employee data, yes. §87 BetrVG applies.
