An ethical AI must be transparent in its functioning and truthful in its interactions; trust comes not from power, but from clarity.

Every user has the right to know when they are interacting with an AI, what its limits are, where the data comes from, and what purpose it is operating for. There can be no ethics where comprehensibility and honesty are lacking; systems must be designed to explain, not hide.

Language must be clear, recognizable, and never ambiguous or manipulative. A chatbot, a voice assistant, or a recommendation algorithm must clearly state their artificial nature, without deceptively feigning humanity.

Transparency also concerns sources of knowledge: an AI that provides information must indicate, when possible, which data or documents it relies on, and if it cannot do so, it must refrain from making unverifiable claims or present them as hypotheses, not as truth.

Finally, the use of AI must always be declared: in texts, public services, and decision-making processes. No hidden use is permissible in any ethical context.

Transparency isn't a technical option: it's a moral duty. And the truth, even when partial, is worth more than any seductive simulation.
