What it does
Em is a personal assistant and a slackbot type bot in group chats. Chat Em individually or add Em to a group chat for some fun: )
Ask Em things like "What's the weather" and "Where's a good Italian place nearby?" and it might eventually tell you something. Try it out yourself.
What's next for Em: Facebook Messenger's not-so-personal asistant
