Cons: Botengine has reduced the workload on the helpdesk department . However ,I fear we may come one day have an advanced Botengine ,years down the line ; which is able to respond to the current complex queries we respond to and thus when that day comes , why would my employer keep me at the job ,when a Bot can do a better job ,without ever getting tired?
Cons: The Learning Academy and help topics are not sufficient to train you to use this product. It took a lot of stumbling through (and still does) on how to figure out what to do and how to train the chatbot. Also - support is only available through email, would be extremely helpful to be able to get help in realtime.... You would think a chat product would have the ability to LiveChat with it's customers!
This chatbot is one the best AI chatbots and it’s my favorite too. Evidently it is the current winner of Loebner Prize. The Loebner Prize is an annual competition in artificial intelligence that awards prizes to the chatterbot considered by the judges to be the most human-like. The format of the competition is that of a standard Turing test. You can talk with Mitsuku for hours without getting bored. It replies to your question in the most humane way and understands your mood with the language you’re using.
