EU AI Act Article 50 Guidelines: What SaaS Must Ship by 2 August 2026

What changed on 20 July

The European Commission published its Article 50 implementation guidelines just before the transparency obligations begin to apply on 2 August 2026.

The deadline did not become a blanket obligation to label every use of AI. The correct first step is to identify which Article 50 case applies, which actor carries the duty, and whether an exception or transition rule is relevant.

The four practical scope questions

These duties are not interchangeable. A chatbot notice does not automatically satisfy output-marking duties, and a website privacy-policy paragraph does not replace a point-of-interaction notice.

What SaaS teams should prepare now

1. Build an AI touchpoint inventory

List every surface where a natural person interacts with AI or receives generated content:

• chat and support widgets;
• copilots and agents;
• generated reports, images, audio, or video;
• automated emails and externally shared outputs;
• emotion recognition or biometric categorisation features.

Record the provider, deployer, intended purpose, audience, launch date, and where the output is used.

2. Separate human-facing disclosure from machine-readable marking

For direct interaction, draft clear copy shown at the point of interaction. For generated or manipulated content, separately assess technical marking and detectability under Article 50(2).

The Commission's materials also provide optional EU icon variants for certain labelling use cases. Using an icon does not remove the need to assess the wording, placement, accessibility, and applicable paragraph.

3. Preserve evidence

Keep a dated record of:

• approved disclosure copy;
• the UI surface and placement;
• screenshots for desktop and mobile;
• product/model version;
• who approved the implementation;
• exceptions or transition rules relied on;
• the source and date of the legal interpretation.

This evidence is useful for counsel, procurement, and a future request from a competent authority.

The limited December 2026 grace period

Do not describe 2 December 2026 as a general Article 50 extension.

The Commission describes a limited transition for the marking and detection obligation in Article 50(2) for relevant generative AI systems placed on the market before 2 August 2026. It does not automatically postpone chatbot interaction notices, deepfake disclosure, emotion-recognition notices, or every other Article 50 duty.

Confirm system dates and the exact paragraph with counsel before relying on the transition.

A practical implementation file

For each AI touchpoint, keep one row with:

Use the Article 50 checklist and disclosure template, or request an Article 50 Evidence Pack for a product-specific implementation file.

Not legal advice. The guidelines support implementation but do not replace the AI Act or product-specific legal analysis.
