I understand what you mean. I don't like it either, but I've yet to find another way of explaining quickly what it does. A CRM for friends is very explanatory. But I dislike the creepiness of it.
Since the app has a person's name anyway, I'd suggest abandoning acronyms entirely and making up something that sounds like a job title: e.g. "Monica, your Personal Assistant." (Which is an actual job title, see https://en.wikipedia.org/wiki/Personal_assistant)
