Developed by one of the leaders in the AI space, IBM, Watson Assistant is one of the most advanced AI-powered chatbots on the market. Pre-trained with content from your specific industry, Watson Assistant can understand your historical chat or call logs, search for an answer in your knowledge base, ask customers for more clarity, direct them to human representatives, and even give you training recommendations to hone its conversational abilities.
Cons: Initial onboarding is wonky and can use UX upgrades. It was difficult understanding how to get started until I watched several videos. I also had issues using this platform on Firefox to connect Facebook messenger. Currently, the workaround is to use Chrome to connect messenger and then you can continue working on Firefox. I don't like having to use a different browser to obtain functionality. The team promised this was a bug that will be ivnestigated
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.
