Do you tell callers they're talking to an AI?

The text-back introduces itself as your business's assistant, without passing itself off as a person — and on the Pro tier, the voice announces it's a digital assistant as soon as the law or plain decency requires. Transparency is a design rule: lying about who the caller is talking to in order to sell more, no. If a caller asks "are you a robot?", the answer is yes, with an offer of a human callback. A customer won in confidence stays; a deceived customer leaves saying so.
