EU AI Act Article 50 Requirements: Transparency Disclosures + Register Method

Chatbot notices, AI-generated content labels, and an Article 50 register tied to AI-015 and AI-006.

Resource guide · Updated 2026 · 17 min read

Organizations deploying AI that interacts with people in the EU — or publishing AI-generated content to EU users — must satisfy Article 50 transparency obligations. The operational question is typically: what to disclose, and how to document compliance for auditors and regulators.

Important: Article 50 is not a “high-risk transparency register.” High-risk rules live in Annex III and Articles 6–17. Article 50 sets transparency obligations for specific use cases, even when a system is not high-risk:

  • AI that interacts directly with people (chatbots, assistants)
  • AI-generated or manipulated content (text, image, audio, video)
  • Deepfakes and synthetic media
  • Emotion recognition and biometric categorization

This guide documents a spreadsheet-first EU AI Act Article 50 method: copy-paste disclosure templates, a trigger-based register, and AI-015 + AI-006 workflow — no separate “log matrix” required.

Legal disclaimer

Operational guidance only. This guide supports EU AI Act transparency planning. It is not legal advice. Obligations depend on role, system type, and implementing acts. Engage qualified EU regulatory counsel for binding interpretations.

Key findings

• Article 50 triggers on 4 use-case patterns (human interaction, AI-generated content, deepfakes, emotion/biometric) — not Annex III high-risk classification alone.
Provider vs deployer determines who drafts vs implements disclosures; map your role before copying templates.
• A trigger-based spreadsheet register + AI-015 disclosure templates is sufficient evidence — most teams document a system in under an hour.

Timeline

Article 50 obligations are among the earlier EU AI Act requirements to take effect. Verify dates against the latest European Commission implementation timeline for your role and system type.

Are You a Provider or Deployer?

RoleDefinitionArticle 50 focus
ProviderDeveloped the system; place on EU marketEnsure disclosures exist and stay accurate
DeployerUse third-party AI serving EU usersImplement notices; adapt provider text for your context

Providers: full register + templates. Deployers: customer-facing columns, implementation log, provider references.

When Does Article 50 Apply?

ScenarioTriggerDisclosure
Customer support chatbotArt. 50(1) AI–human interactionInform users they interact with AI at start
AI marketing copyArt. 50(2) AI-generated contentLabel content as AI-generated
Deepfake / synthetic videoArt. 50(3) deepfakesDisclose artificial generation/manipulation
Emotion recognition in hiringArt. 50(4)Notify individuals; may overlap Annex III high-risk
Voice assistant in appArt. 50(1)Disclose at first interaction + settings

When uncertain, document rationale and review quarterly. Over-inclusion is a documentation issue; under-inclusion is regulatory risk.

Readiness self-check

  • We identify all systems triggering Article 50

Quick start (1 hour)

  1. Match one system to the trigger matrix
  2. Select an AI-015 template (A–D below)
  3. Populate one row in the CSV register
  4. Publish notice in UI, footer, or onboarding
  5. Log version + date in register CHANGELOG

Customer Disclosure Pack (AI-015 Aligned)

Template A — AI–human interaction (chatbots)

You’re chatting with an AI assistant This conversation is powered by artificial intelligence. • Purpose: [e.g., account support questions] • Limitations: Responses are automatic and may be inaccurate. • Human support: Type “agent” or click [link] anytime. • Contact: ai-transparency@company.com

Template B — AI-generated content

AI-Generated Content Notice This [article/image/audio/video] was created with AI assistance. • How used: [e.g., AI draft; human editors reviewed] • Questions: content-ai@company.com

Template C — Deepfake / synthetic media

Synthetic Media Disclosure This content was artificially generated or manipulated using AI. • What was modified: [e.g., voice synthesized for narration] • Purpose: [e.g., multilingual distribution] • Contact: comms-ai@company.com

Template D — Emotion / biometric categorization

Notice: Biometric/Affective Analysis in Use This system uses AI to [analyze emotions / categorize individuals] based on [data type]. • Purpose: [e.g., interview feedback] • Your rights: Opt out, request explanation, human review • Contact: privacy@company.com

AI Chatbot Disclosure (Art. 50(1))

Compliant checklist

  • Notice before or at start of first interaction
  • Plain, concise language (not buried in privacy policy only)
  • Clear human escalation path
  • Re-accessible in chat header or settings
  • Monitored contact channel

AI-006 + AI-015 Integration

AI system in AI-006 register ↓ Assess Article 50 trigger ↓ Add row to Article 50 register (if applicable) ↓ Select AI-015 template → publish → log version ↓ Quarterly review + CHANGELOG

One technical source of truth (AI-006); transparency derived from it via AI-015. Inventory unsanctioned systems first with the shadow AI spreadsheet. Deployers: verify provider Article 50 posture via the vendor questionnaire.

Documentation gaps to avoid

  • Notice only after interaction starts
  • Overly technical language
  • No dedicated contact channel
  • No disclosure_text_version tracking
  • Deployer assuming provider handles UI implementation

FAQ

Provider or deployer?
Document per system. Many orgs are both — you may be provider for your product and deployer for a third-party API.
Open-source models?
Exemptions are narrow. If you deploy for covered use cases, fine-tune, or charge for access, obligations may still apply. Get legal counsel.
How detailed must disclosures be?
Enough to understand it’s AI and what that means — concise and plain language. Example: “This chat is with an AI assistant. Type ‘agent’ for a human.”
Per member state?
EU-wide rule; disclosures must be in languages your users understand. Document language coverage in the register.
GDPR overlap?
Article 50 complements GDPR Arts. 12–15. Integrate in privacy notice or dedicated AI transparency page; document approach in register.
Embedded in third-party platforms?
If UI limits notices, document constraint and use compensating controls (email pre-notice, help center page).
