EU AI Act Article 50: AI transparency duties for online stores

What Article 50 is really about

The EU AI Act is a broad law, and most of it deals with high-risk AI systems that a typical store never builds or sells. Article 50 is different. It sits in the transparency chapter and covers everyday uses of AI that people interact with directly. For an online store, that usually means two situations: an AI system that talks to shoppers, such as a chatbot or shopping assistant, and AI-generated media that a shopper sees, such as a synthetic image of a person.

The point of the rule is simple. People have a right to know when they are dealing with a machine rather than a human, and when an image or video that looks real was actually produced or altered by AI. Article 50 turns that principle into a set of concrete duties, and it splits those duties between the party that builds the AI system (the provider) and the party that puts it to use (the deployer).

Who is the deployer? (that is you)

Article 50 assigns different duties to different roles, so the first job is to work out which role you are in. A provider is the party that develops an AI system and puts it on the market under its own name. A deployer is the party that uses an AI system in the course of its business. When you install a third-party AI chatbot app, or use a tool that generates model imagery, you are almost always the deployer, not the provider.

This distinction matters because some Article 50 duties fall on the provider and cannot be discharged by you. For example, the obligation to build machine-readable markers into AI output sits with the provider of the generation tool. As a deployer, your side of the bargain is the perceptible, human-visible part: making sure a real person can see, in plain language, that AI is involved. Aclara is built around this deployer view, so it never tells you to satisfy a duty that is not actually yours.

The two situations that matter to a store

1. Interacting with an AI system

If a shopper can chat with an AI on your store, they should be able to tell it is AI and not a human agent. Under Article 50 the core duty to design that disclosure into the system sits with the provider of the chatbot. As the deployer, adding your own clear notice is the simplest and safest way to stay on the right side of the rule, and it is easy to get right. We cover the exact wording and placement in the AI chatbot disclosure guide.

2. AI-generated or manipulated content

If you publish AI content that imitates real people or real scenes, the kind of image or video a shopper could mistake for a genuine photograph, that content should be marked as artificially generated or manipulated. This is aimed at synthetic imagery of people, such as AI fashion models or virtual try-on, rather than ordinary product photography. Plain AI-assisted product shots, tidied backgrounds and upscaled images are generally outside the marking duty. The practical line is drawn in the AI-generated images and content guide.

A note on AI-written text

AI-written text has a narrower rule than many store owners expect. The deployer marking duty for text applies to content published to inform the public on matters of public interest, think news, health or civic topics, not to commercial copy. An ordinary product description written with AI help and then reviewed by a person is commercial content and generally needs no disclosure. This is one area where over-labelling is unnecessary, so it is worth being precise rather than slapping a badge on everything.

The timeline: 2 August 2026

The Article 50 transparency obligations apply from 2 August 2026. That is the date a store should aim to have its disclosures live and correct. Because the rule is about what shoppers can see on your storefront, getting ready is mostly a storefront task: identify where AI shows up, add the right notices, and keep them working as your theme changes. There is no filing or registration step for a deployer in this part of the law.

Scope: which stores this reaches

Article 50 follows the output, not your postal address. If shoppers in the EU interact with your AI system or see its output, the transparency duties apply, even if your company is registered elsewhere. In practice, if you sell into any EU market and use an AI chatbot or AI imagery of people, you should assume you are in scope and plan accordingly. If you use no customer-facing AI at all, there is nothing here for you to disclose.

How to get ready, step by step

1. Map your AI touchpoints. List every place a shopper meets AI: chat widgets, assistants, generated imagery, and any AI text on public-interest topics.
2. Sort each one by role. For most stores the chatbot notice is a sensible deployer backstop, and the image marking duty applies only to synthetic imagery of people.
3. Add clear, human-readable notices where they belong: a chat notice at the point of conversation, an AI label near the affected image or media.
4. Translate the notices for the EU languages you sell in, so the disclosure is genuinely understandable to the shopper who sees it.
5. Keep it live. Verify the notices still render after theme edits, and keep a dated record of what you disclosed and when.

Where Aclara fits

Aclara is a configuration tool for exactly these steps. It asks a few questions about how your store uses AI, tells you which Article 50 disclosures actually apply to you as a deployer, adds a chat notice and an AI-content label to your theme, auto-translates them into 24 EU languages, then reads your live theme to confirm the notices are really showing and keeps a dated, hash-chained record. It reads your theme with a single read-only permission and stores no customer data.

Frequently asked questions

Does Article 50 apply to my store if I am not based in the EU?

Yes. The obligations bite when your AI systems are used by, or their output reaches, people in the EU, whatever country your business sits in.

Am I the provider or the deployer of the AI I use?

A merchant who switches on a third-party AI chatbot or image tool is normally a deployer, not the provider. That split decides which Article 50 duties are yours.

When does Article 50 start to apply?

The Article 50 transparency obligations apply from 2 August 2026. That is the date to plan your storefront disclosures around.

Do ordinary product photos need an AI label?

Usually not. The deployer marking duty targets AI content that imitates real people or scenes. Plain AI product shots, cleaned-up backgrounds and upscaling are generally out of scope.
