Article 50 AI Act Transparency Response Letter

Article 50 AI Act Transparency Response

Article 50 of the EU AI Act sets transparency obligations — telling people when they are interacting with AI and marking AI-generated or synthetic content. Article 50 duties have applied since 2 August 2026. Providers whose generative systems were already on the market before that date have until 2 December 2026 to comply with the marking obligation in Article 50(2), under Regulation (EU) 2026/1744. When a regulator or partner asks how you comply, your response should set out your disclosure, your labelling/marking approach, and your user notice. DocuGov.ai drafts that response.
