I appreciate that this is open source... seems more like a proof of concept though rather than an actual product... "Optimist Prime is a Facebook Messenger Bot that supports Voice Recognition, Natural Language Processing and features such as: search nearby restaurants, search trending news, transcribe and save memos to the cloud. It also save user data (with permissions, of course) such as favorite locations, can provide customized greetings (acknowledging user's time in any time zone, i.e. Good morning/Good evening) and entertaining responses, etc."
