The title seems like clickbait but also reflects an annoyance/frustration with overuse as marketing/sales tends to do. I ignore that and ask what exactly does your product do, then decide how to categorize it. My hand-wavy definition is basically as a chatbot gives an AI multi-modal input and output to a user, an agent has 'hands' which can produce an effect on a system rather than reporting to the user directly via media. The method of integration isn't really important, it could be using a public network API or as part of a compiled static binary, whatever.
