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