Since one of the most popular chatbot uses is to automate customer service, a chatbot's abilities to answer user questions is directly related to brand image and customer satisfaction. Previously, I talked about how to create a Q&A chatbot in a few minutes to answer users' free-text questions and handle complex, multi-turn Q&As, all without coding. Because no chatbot is perfect, I also mentioned how to teach a chatbot handle unknown user questions and further improve customer satisfaction.
