Tidio and Lyro: AI notice duty (Article 50)

Lyro answers on its own. On a French or EU site, the visitor must know from the first message.

Tidio offers live chat and the Lyro agent. As soon as replies go out without a human behind them, Article 50(1) of Regulation (EU) 2024/1689 requires a clear notice, at the latest when the chat opens.

Small businesses that install Tidio to “cover support at night” are in scope: there is no size threshold. A tiny “AI” chip or a FAQ link does not replace a readable sentence next to the widget.

Tidio remains the tool vendor. The site remains responsible for displaying the notice, keeping a register (Tidio / Lyro / support use) and being able to show that the notice appeared on a given day.

Clairia detects code.tidio.co and Tidio markers on the homepage. This is not a Tidio audit, nor legal advice.

The path, in order

  1. 1

    Scan the homepage

    Paste the URL. In under a minute you see whether a known chatbot is present, and whether a notice is visible. With no chatbot there is no /100 score.

  2. 2

    Show the notice next to the chat

    One script line (w.js) sits on Crisp, Intercom, Tidio and known widgets. On Crisp, the sentence is also shown once in the conversation.

  3. 3

    Re-scan the homepage

    Clairia should appear in the findings. This is not a certification: it confirms the script is on the page.

  4. 4

    Let the log run

    Each page load with the script is dated. It is not proof that the chat was opened.

Frequent questions

Who must show the notice: the site or the chat vendor?
The visitor is talking to your site. The vendor (Crisp, Intercom, Tidio…) provides the tool. The site must inform, at the first interaction.
Is a notice in the terms or legal notice enough?
No. Too late and too easy to miss during the chat. Article 50 requires clear information at the latest at the first interaction.
How do you prove the notice was shown?
A useful file: a register (tool, vendor, use), a dated log of script loads, homepage scans. A /100 score is not proof.

General information, not legal advice.
