Brevo Conversations and Article 50: who shows the AI notice?
Formerly Sendinblue: Brevo chat and bots are yours vis-à-vis the visitor. Notice when the widget opens, not only in the terms.
Brevo (formerly Sendinblue) runs on many French small businesses. Conversations and automated replies are not “obviously human” once a bot qualifies or answers. Article 50(1) then requires a clear notice at the first interaction.
Brevo’s privacy policy, or a paragraph in your legal notice, is too late during the chat. A readable sentence on the widget, in the page language, is the useful minimum.
Brevo provides the tool. The site keeps the register (Brevo Conversations, support/leads use) and, if possible, a display log of the notice on its domain.
Clairia detects conversations-widget.brevo.com and Sendinblue markers on the homepage. Help with compliance, not a Brevo certification or 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.
