Eu Ai Act Content Disclosure

EU AI Act Content Disclosure (Article 50)

> DISCLAIMER: Guidance only. Verify with legal counsel for your specific use case.

When to Use

• Publishing AI-generated content (text, images, audio, video)
• Deploying chatbots or conversational AI in the EU market
• Distributing synthetic media (deepfakes, voice clones)
• Adding AI disclosure to existing products
• Marking AI-generated music, podcasts, or video content

Disclosure Templates by Content Type

Chatbot / Conversational AI

Place before first user interaction:

This service uses artificial intelligence. You are interacting with an
AI assistant, not a human. Responses are generated automatically and
may contain errors.

AI-Generated Text (Articles, Reports)

Place at the beginning or end of the content:

This content was created with the assistance of artificial intelligence.

AI-Generated Images

Visible watermark or caption:

Image generated by AI

Metadata (EXIF/XMP):

true
model-name
2026-04-22

AI-Generated Audio (Music, Voice, Podcasts)

ID3 tags (MP3/FLAC):

TXXX:AI-Generated=true
TXXX:AI-Model=model-name
TXXX:AI-Generation-Date=2026-04-22

Visible on distribution platforms:

Generated by AI (EU AI Act Art. 50)

Synthetic Voice

Before or during audio playback:

This voice is generated by artificial intelligence.

Deepfake / Synthetic Video

Prominent, visible marking:

⚠️ This video content was generated or manipulated by AI (EU AI Act Art. 50)

Implementation Checklist

1. [ ] UI disclosure before first AI interaction (chatbots)
2. [ ] Metadata tags on all AI-generated files (EXIF, XMP, ID3)
3. [ ] Visible marking on published content
4. [ ] API response headers for AI-generated content: X-AI-Generated: true
5. [ ] Distribution platform descriptions updated
6. [ ] Internal documentation of AI systems used
7. [ ] Process for handling mixed human+AI content

Exceptions (No Disclosure Required)

• AI used only for internal development (not user-facing)
• AI used as a tool but human substantially edits the output
• Law enforcement exceptions (specific conditions in AI Act)
• Artistic expression exceptions (limited, case-by-case)

Penalties for Non-Disclosure

Up to EUR 15M or 3% of global annual turnover (whichever is higher).

What This Skill Does NOT Do

• Does not implement watermarking algorithms
• Does not modify media files (provides templates and metadata specs)
• Does not determine if content qualifies as "AI-generated" (legal determination)
• Does not cover copyright of AI-generated content (separate issue)
