Tidio and the EU AI Act: does your chat widget tell people it's AI?

Applies from 2 Aug 2026Fines up to €15M / 3% turnoverLast reviewed July 2026

Tidio's Lyro is pitched at small e-commerce and service businesses that want an AI agent running with minimal setup — which is exactly the profile most likely to ship with defaults untouched. If you installed Tidio, turned Lyro on, and moved on, the odds are good nobody ever asked whether the first message tells EU visitors they're talking to AI.

The rule itself is short. Article 50(1) of the EU AI Act requires AI systems that interact directly with people to be designed so users know they're dealing with AI — no later than the first interaction, in a clear and distinguishable way. The exception for cases where it's "obvious" is narrow: a natural-language customer-service bot doesn't qualify just because it has a robot icon. A line in your terms of service doesn't satisfy it either. And it's easy to enforce, because a regulator can simply open your site and start a chat.

Who's on the hook? Responsibility is split: Tidio carries provider-side duties for the system itself, but how the widget is configured and presented on your site is your deployment. If the disclosure setting exists and isn't enabled — or the notice is hidden — that gap is yours.

Where the disclosure lives in Tidio

In a typical Tidio setup, the surfaces that can carry (or fail to carry) the AI disclosure are:

The chat widget bubble and welcome message shown before a visitor types
Lyro's display name and avatar in the conversation view
Lyro's first generated answer to a visitor question
The takeover moment when a human operator joins or replaces Lyro

Your Tidio disclosure checklist

Open your storefront in a private window, start a chat, and check whether anything identifies Lyro as AI before the first exchange
Set Lyro's name and description to something honestly AI ("Lyro — AI assistant"), not a human persona
Edit the welcome message to state the AI nature in plain language
Check the widget on mobile — small-screen layouts sometimes hide descriptors that show on desktop
Verify the operator-takeover notification is visible to the visitor, not just internal
Screenshot the widget's first-interaction state monthly and after any Tidio settings change

Keep proof. On a complaint, an authority will want to see that the disclosure was there and how it was designed. Keep timestamped screenshots of the first-interaction state, your widget configuration, and a record of when each was last changed — that evidence file is the difference between "we comply" and "we can show we complied."

Watch out for

Small-team deployments fail through neglect rather than intent: nobody owns the widget after launch, Tidio ships interface updates, seasonal staff rename the bot for a campaign, and six months later the live widget no longer matches anyone's memory of it. For a small merchant, the fix is minutes of configuration — the exposure comes from never checking.

Note: vendor interfaces and setting names change. This page describes where disclosure surfaces typically live in Tidio as of July 2026 — verify the exact toggles in your own Tidio workspace and against Tidio's current documentation.

Common questions

We're a small shop — do EU fines really apply to us?

The obligations apply to systems interacting with people in the EU regardless of company size; enforcement priorities are a separate question you don't control. Given the fix is a welcome-message edit, being small is a reason to comply cheaply, not to skip it.

Lyro sometimes hands off to us in the same window — does that need anything?

Yes — make the participant change visible. The clean pattern is an automatic line announcing the human takeover, so the visitor always knows whether they're talking to Lyro or to you.

DisclosureProof opens your site the way a regulator would, triggers your Tidio widget, and records whether the AI disclosure actually appears — with timestamped evidence either way. Free scan at launch.
