How should I explain the difference to a sceptical client?

Say this: a chatbot is a mouth; a Digital Twin is the brain, memory and structured information behind the mouth. If the business wants useful answers, it needs the brain, not just the mouth.

That usually gets the point across quickly without technical jargon. A Digital Twin is broader than a chatbot because it includes approved business facts, public Q&A, image context and machine-readable outputs, not just a chat box. Used well, this becomes a clear business conversation rather than a generic AI sales pitch. In the SupplyOnly.com model, the point is to make this useful rather than decorative: connect the answer to approved business facts, public Q&A, image context and the Own The Conversation fulfilment pathway. That gives a referrer or client a clearer reason to act without pretending that AI visibility is magic or guaranteed.
