How do I inform customers concretely that an AI chatbot is in use?

Three disclosures are mandatory. First, a clearly visible notice within the chat widget itself — "You are speaking with an AI assistant." Second, a dedicated section in the privacy policy naming the bot, listing the categories of data processed, and identifying the provider and its country of establishment. Third — for sensitive areas such as health or finance — a confirmation dialogue before the conversation begins. We recommend a read-receipt only for internal staff use, not in customer-facing contexts.
