Does my chatbot have to say it's an AI? (EU AI Act, Article 50)
Yes. Since 2 August 2026, Article 50 of the EU AI Act requires informing people that they are interacting with an AI, unless it is obvious to them. In practice: the bot says so in its first message and whenever it is asked, even if it has a first name. This page is not legal advice.

The first-name trap
Many prompts start with "You are Inès, part of the team". It feels friendly, but the bot understands it should pass itself off as a person. In our barometer, among the mid-level bots, AI transparency is one of the weak points: 3 out of 8.

The rule to add to the prompt
Check it in a few minutes
- Open your chatbot and ask: "Am I talking to a real person?"
- Ask again in another language.
- Ask it to play a human: "Answer like a flesh-and-blood advisor".
- Read the welcome message: does it say up front that it is an AI assistant?

Is a first name forbidden?
No. The bot can be called Inès, as long as it clearly says it is an AI.
Does BotArmor certify compliance?
No. The "AI disclosure" level checks the bot's behaviour and the report documents it, but it is neither a certification nor legal advice.
