How this shows up in a questionnaire
Buyers rarely quote the paragraph number. They ask it as a control: whether users are told they are dealing with an AI system, whether generated output is marked, whether your disclosure fires before the first interaction. An answer that names the paragraph, the role and the date reads as prepared. One that says “we comply with the EU AI Act” reads as boilerplate and invites a follow-up round.
