Pros: It's system is more advanced comparing with Manychat or Chatfuel (both are like toys if you try Activechat). It has autorresponders of course, but also suitable for flexible AI conversations. Is like coding an advanced chatbot without needing to be a coder. The team is very responsive and their founder Andrii has a clear vision about this project.
Pros: Botengine was easy to integrate with our existing Livechat helpdesk program . I am impressed with the ease at which Botengine is able to respond to the most popular of simple questions we get from our customers like; the address of the company , what we do , our subscription rates etc While these questions may appear to be straight forward , they are the most asked question which our customers throw at us . With the coming of Botengine ,we no longer need to bother ourselves with these sort of questions ; Botengine responds to them ,while we await the tough ,complex queries.
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.
