Ok - thanks. I'm not sure there is a bright-line distinction, then.
I use a set of chat-bot related APIs to implement CLIs for various EHR-related and clinical-related applications (Navigating kajillions of options in EHR menus requires, famously, too many damn clicks. Physicians are intelligent enough to learn simple syntax to avoid all that crap)
I'm probably using the wrong words when I describe it, but when I tell developers in the ecosystem that we have a "chatbot-like" interface, people seem to get it, so I haven't upgraded my nomenclature.
