EU AI Act Article 50 Checklist

disclosureproof.com/eu-ai-act/checklist/ · applies from 2 August 2026 · reviewed July 2026

  1. Chatbot & AI-interaction disclosure (Art. 50(1))

    • Open your site in a private window as a first-time EU visitor and start a chat. Is it explicit you're talking to AI, before or in the very first exchange?
    • Check the mobile view separately, since disclosures configured on desktop can vanish in compact layouts.
    • Check every channel you deploy to (web widget, WhatsApp, voice, app). A disclosure verified on one doesn't confirm the others.
    • Check human-handoff moments make the participant change clear, in both directions.
    • Confirm the AI persona's name/avatar doesn't read as human with no accompanying AI indicator.

  2. Machine-readable marking (Art. 50(2))

    • Download a few published images and inspect their metadata for C2PA / Content Credentials or IPTC provenance fields.
    • Test your actual publishing pipeline (CMS, CDN, image optimizer). Marking present at generation is often stripped before it reaches your live page.
    • Note: the marking duty for generative systems already on the market before 2 Aug 2026 is deferred to 2 Dec 2026; everything else on this page still applies from 2 Aug.

  3. Deepfake & AI-text labels (Art. 50(4))

    • Open your latest AI-assisted or AI-generated article. Is there a visible label a reader would notice, outside a footer or metadata entry?
    • Check any AI-generated or AI-manipulated image/audio/video that resembles a real person, place, or event for a clear label.
    • Consider using the official EU icons (AI / AI GENERATED / AI MODIFIED), free, and a stronger signal than an improvised badge.

  4. Keep evidence

    • Screenshot everything you verified above, with dates.
    • Save your chatbot/widget configuration export alongside the screenshots.
    • Re-run this checklist after any platform update, redesign, or vendor migration; settings drift is the most common way a compliant setup quietly stops being compliant (six ways it happens silently).

Informational only. Not legal advice. A checklist reports what to look for; it can't declare you compliant, since parts of Article 50 aren't externally observable. For a hands-off version of steps 1–3 with dated, hash-verified evidence, run the free scan at disclosureproof.com/scan/.
