From 2 August your chatbot has to admit it is an AI

It is a European regulation, it applies by itself, there is nothing to apply for, and almost everyone who breaches it will be caught by the same thing: a customer-service chat on the website that does not say what it is.

Regulation (EU) 2024/1689, the one everybody calls the AI Act, has been coming into force in stages since 2024. The part arriving now is article 50, and it is the first to touch ordinary businesses: not those who build artificial-intelligence models, but those who simply use them. An accountancy practice with a chatbot on its website. A shop with automatic replies on WhatsApp. A garage posting AI-generated images on social media.

The date is 2 August 2026. And no, it has not been postponed.

What exactly it requires

Article 50 does not regulate what AI may do. It regulates that people know there is an AI behind it. They are transparency obligations, and they come down to four:

The notice has to be given at the first interaction, clearly and accessibly. Burying it in the privacy policy does not count.

For the vast majority of Spanish small businesses, complying with article 50 means writing one sentence. The problem is not the difficulty: it is not knowing it exists.

Who it really applies to

Here is the commonest misunderstanding. Many people assume this is about big tech. Article 50 distinguishes between the provider (whoever develops the system) and the deployer (whoever uses it in their business). The obligations to tell the user and to label deepfakes fall on the second.

In other words: if you have bought a chatbot from a supplier and have it on your website, the obligation for that chatbot to say it is an AI is yours, not the seller's. Whether the supplier makes it easy for you is another matter; liability before the authority rests with whoever deploys it.

Quick test: does it apply to you?

Go through this list thinking about what you have published today.

YESA chat on your website or WhatsApp that answers by itself, even with AI-prepared replies.
YESSocial-media posts with AI-generated images or videos.
YESBlog articles written with AI and published without anybody reviewing them.
YESAn answering machine or telephone message with a synthetic voice that interacts with the customer.
NOOCR that reads data from your invoices: it extracts, it does not generate content.
NOVoice dictation that fills in a form using fixed rules.
NOThe automation you have always had: rules, templates, calculations. That is not AI.

The dates, unadorned

2 Aug 2026
The article 50 transparency obligations start to apply. Notice that “you are talking to an AI”, labelling of deepfakes and of text on matters of public interest.
2 Dec 2026
End of the transition period for art. 50.2 (machine-readable marking of synthetic content) for systems already on the market before 2 August. It affects that paragraph only.
In progress
The Spanish AI governance act —the one designating AESIA as the authority and setting out the penalty procedure— is still a bill before Parliament. The European Regulation, by contrast, applies directly without waiting for it.

What happens if you do not do it

Article 99 of the Regulation places a breach of article 50 in a band of up to €15 million or 3 % of worldwide annual turnover, whichever is higher.

Before you drop your coffee: for small businesses and start-ups the Regulation itself reverses the rule and applies the lower of the two figures, and penalties are graded by seriousness, duration, size and cooperation. Nobody is going to fine a four-person practice €15 million over an unlabelled chatbot. But the breach exists, and avoiding it costs literally one afternoon.

What we would do this week, in order:

1. Open your website and see whether you have a chat. If you do, add something to the first message like “Hello, I am [company]'s virtual assistant. You are being served by an AI; if you would rather talk to a person, just say so.”

2. Ask your chatbot supplier whether they cover the synthetic-content marking or whether you have to switch it on yourself.

3. If you publish AI-made images or videos, add the notice in the caption. The European Commission has published icons for this — using them is voluntary, but labelling is not.

4. Write it down. If you are ever asked, what counts is being able to show what you did and when.

Why we are the ones telling you

Factuza is VeriFactu invoicing software. It has nothing to do with chatbots. And yet this is our first newsletter, for one reason: article 50 is the perfect example of the kind of rule that sinks a sole trader or a small business. It does not make the general press, your accountant does not mention it because it is not a tax matter, no letter arrives, and one day you are simply in breach.

The same goes for VeriFactu, incidentally. The obligation is 1 January 2027 for companies and 1 July 2027 for the self-employed, and there are still people who believe it was postponed indefinitely.

And while we are here: we do not use generative AI in Factuza

The two features of ours that look most like it are not. Invoice dictation uses the device's own speech recognition plus an interpreter built on fixed rules. Expense OCR is an extraction model: it reads what the paper says, it does not invent anything.

The same inputs always give the same outputs, and every figure Factuza calculates records where it came from. In a program that touches your taxes that strikes us as the bare minimum. It is why we can tell you about article 50 without selling you anything.
