I have been using this bot for almost a month. Like any machine-based-learning project, it could be mistaken occasionally at the beginning. With some "training" - adding more items to enrich the docs, it is growing smarter. Do not intend to make it a total replacement of human agent, yet it is your saver from redundant and repetitious choirs and much more than that. BWT, my visitors love it. Their conversations are really amusing sometimes. Anyway, using this bot is a big pro for people fond with playing around A.I. while watching what it can be used for.
