Introduction — why this notice exists

Regulation (EU) 2024/1689 of the European Parliament and of the Council on artificial intelligence (the “EU AI Act”), specifically Art. 50, requires operators of AI systems that interact with natural persons to inform those persons that they are communicating with an AI system. This information must be provided clearly, comprehensibly and no later than at the start of the first interaction.

This AI System Transparency Notice (the “Notice”) serves three purposes:

• It informs website visitors about the nature of the Awentail AI assistant and how it works.
• It provides Awentail customers (website operators) with sample texts and guidance for meeting the transparency obligation under Art. 50 of the AI Act.
• It serves as Awentail’s internal documentation record of the measures taken to ensure compliance with the AI Act.

Awentail provides a technology platform for operating AI assistants. The specific manner in which an AI assistant is deployed on a website, its configuration, and the way visitors are informed is the responsibility of the operator of that website (the Deployer). Awentail is not liable for how a Deployer deploys the AI assistant or presents it to its users.

For the purposes of Regulation (EU) 2024/1689 (EU AI Act): the Awentail platform acts as the provider of the AI system within the meaning of Art. 3(3) of the AI Act. A customer who deploys the AI assistant on their website acts as the deployer of the AI system within the meaning of Art. 3(4) of the AI Act. This allocation of roles is key to determining regulatory responsibility.

ℹ As Deployers under the AI Act, Awentail customers are primarily responsible for informing their visitors. This Notice provides them with the tools to meet that obligation.

PART I — Information for website visitors

This part is intended for visitors of websites on which the Awentail AI assistant is deployed.

What is the Awentail AI assistant?

The chat you are currently communicating with is operated by an automated artificial intelligence system (an AI assistant) — not a live human. The AI assistant was created and configured by the operator of this website using the Awentail platform (Digital D&A s.r.o.).

How does the AI assistant work?

The AI assistant answers your questions based on information provided to it by the website operator (documents, web pages, internal data). It generates responses automatically using large language model (LLM) technology, which may be provided by third parties. Neither Awentail nor the website operator has full control over the outputs of these models.

Awentail provides only the technology infrastructure enabling the AI assistant to operate. The content of the AI assistant’s responses is generated automatically based on the configuration and data provided by the website operator. Awentail does not perform editorial review of individual responses and bears no content liability for them.

⚠ The AI assistant may occasionally provide inaccurate or incomplete information. Its responses do not constitute legal, financial, medical or other professional advice and must not be regarded as a binding position of the website operator or the Awentail platform. For important decisions, always verify information with a relevant expert or a human representative of the company.

What data about you does the AI assistant process?

When communicating with the AI assistant, the following data may be processed:

• The content of your messages and queries.
• Contact details (e-mail, phone) if you voluntarily provide them during the conversation.
• Technical session identifiers (session ID, conversation time).

The controller of this personal data is the operator of the website on which you communicate with the AI assistant. Detailed information about the processing of your data can be found in that website’s privacy policy.

Do you have the right to communicate with a human?

Yes. If you wish to be served by a live agent, tell the AI assistant or contact the website operator directly via the contact details listed on the website. The availability of a human operator depends entirely on the operator of the given website — Awentail is not responsible for it. The website operator is responsible for enabling escalation to a human operator in cases where the nature of the matter requires it.

PART II — Guidance for Awentail customers (Deployers)

This part is intended for Awentail customers — businesses and individuals who deploy an AI assistant on their websites.

Your obligation under Art. 50 of the EU AI Act

As a Deployer of an AI system, you are primarily responsible for informing your visitors that they are communicating with an AI and not a human. This obligation applies from 2 August 2025 for new systems (and generally from 2 August 2026).

⚠ Failure to comply with the transparency obligation under Art. 50 of the AI Act may lead to a fine of up to EUR 7.5 million or 1.5% of worldwide annual turnover, depending on the type of infringement and whichever amount is higher.

A customer must not configure the AI assistant in a way that could give visitors the impression that they are communicating with a natural person — for example, by assigning an exclusively human name without any indication of its AI nature, or by explicitly instructing the AI assistant to deny its artificial origin. Breaching this prohibition is a direct violation of Art. 50 of the EU AI Act and of these rules.

How to meet the obligation — checklist

⚠ Awentail is not liable for a Deployer’s failure to meet the transparency obligations under the EU AI Act where the Deployer does not implement the recommended measures set out in this document. This Notice is informational and does not replace an individual legal assessment of the AI system’s implementation in the Deployer’s specific deployment context.

PART III — Sample texts for implementation

Below are ready-made sample texts that an Awentail customer may use directly or adapt to their needs.

A. AI assistant welcome message (system prompt — instruction for the AI)

Insert into the system prompt of your AI assistant in the Awentail settings:

You are the AI assistant of [COMPANY NAME]. You are an automated system — not a live human. At the start of every first conversation, introduce yourself to the user as an AI assistant. If a user directly asks whether you are human, always answer truthfully that you are an AI. If the user wants to speak to a live human, offer them a contact: [PHONE / E-MAIL / LINK TO CONTACT PAGE].

B. Welcome message shown to the user (first message in the chat)

Set as the AI assistant’s first automatic message:

Hello! I’m the AI assistant of [COMPANY NAME]. I’m an automated system — not a live human. I’ll be glad to help you with questions about [AREA — e.g. our products / bookings / customer support]. If you’d like to speak to our team, just let me know and I’ll pass on a contact.

C. Informational text for the website (footer, privacy policy or standalone page)

We recommend placing the following text on the website (in the footer, cookie bar or privacy policy):

This website uses an AI assistant operated by the Awentail platform (Digital D&A s.r.o.). The AI assistant is an automated system — not a live human. Your queries and any contact details you provide are processed in accordance with our privacy policy. More information: [LINK TO PRIVACY POLICY].

D. Short text for a cookie bar or consent banner

This website uses an AI chat assistant. It is an automated AI system, not a live agent. More in our privacy policy.

E. Sample AI assistant response to the direct question “Are you human?”

No, I’m not a live human. I’m an AI assistant — an automated system created to help you with your questions. If you’d like to speak to our team, I’ll be glad to connect you. Just type “I want to speak to a human”.

PART IV — Technical implementation in the Awentail platform

Awentail provides the following technical means for meeting the transparency obligation:

ℹ By default, Awentail configures the AI assistant so that, when directly asked about its nature, it always answers truthfully that it is an AI system. Customers must not disable this default behaviour.

PART V — Exemptions from the transparency obligation under Art. 50 of the AI Act

Art. 50 of the AI Act provides an exemption from the obligation to explicitly inform users where the AI nature of the system is obvious from the context (the “obvious AI” exemption). Awentail interprets this exemption conservatively:

⚠ Awentail recommends always explicitly informing users about the AI nature of the assistant, even where you believe the exemption applies. The risk of a penalty for non-compliance outweighs the cost of implementing a transparent welcome message.

PART VI — Awentail internal documentation record

This part serves as an internal record of the measures taken by Awentail to ensure compliance with Art. 50 of the EU AI Act. It may be submitted to supervisory authorities or during due diligence.
