There are two main chatbot types:
Rule-based and AI-based chatbots.
With a rule-based chatbot, possible user queries and potential answers are defined in advance. If a question is asked that has not been previously defined, the chatbot will not be able to assist in answering the question.
In contrast to rule-based bots, chatbots based on Artificial Intelligence are able to process natural language. This is done with the help of Natural Language Understanding (NLU). AI-based chatbots are able to learn semi-automatically.
Which type of chatbot is best suited for your company mainly depends on the following two factors.
For example, if you need a chatbot that should only perform a very limited number of clearly defined tasks, it is sufficient to use a rule-based bot. An AI-based bot makes more sense if the chatbot is used for different tasks or to solve more complex problems. Rule-based bots are often used for marketing purposes, such as distributing information or offers, while AI-based chatbots are more common in customer service.
Another crucial factor to consider is the budget and time available to implement the chatbot bot. In general, a rule-based bot can be implemented much cheaper and with less work.
