Responsible and transparent AI—key themes in PMI-CPMAI—require that end users understand when they are interacting with an AI system rather than a human. In this scenario, end users mistakenly believe they are chatting with a person and become frustrated when responses are nonsensical. PMI-style responsible AI and ethics guidance emphasizes clear disclosure, user awareness, and expectation management as essential controls to protect trust and reduce harm.

The most direct way to support transparency here is a disclosure notice with each use (option C), for example a visible label or brief statement indicating “You are interacting with an AI-powered chatbot.” This can appear at session start, in the chat header, or near the input box and may be reinforced periodically.

Inclusion of diverse datasets (option A) and interpretable models (option D) are important for fairness and explainability but do not solve the misunderstanding about the chatbot’s identity. Operationalizing advanced algorithms (option B) might improve answer quality, but again, it does not address the core transparency issue. Therefore, to ensure users know they are engaging with an AI chatbot, the system should present a clear disclosure notice with each use.
