A chat bot is a humanlike conversational character.
Its conversational skills and other humanlike behaviour is simulated through artificial intelligence.
It often acts as a virtual assistant and it can have its own visualisation through an avatar
or it is faceless. We expect that through the years every conversational chat bot will grow into a real virtual human.
