There are a quite a few now. The barrier to entry for natural language processing has been lowered to a point where there has been a proliferation of chat-bots attempting to replace people. These AI models are learned by scanning the corpus of FAQ's and customer service training materials for a specific company. So far, in my experience... they don't work all that well. Although to be fair, it might be entirely psychological. When you're speaking with a human, you feel as if there is a possibility for improved understanding. When you're talking to a robot which doesn't understand you, that's a pretty hard barrier.
