The technology used to power chatbots in customer service typically includes artificial intelligence (AI), particularly through techniques like natural language processing (NLP). NLP allows chatbots to understand and respond to human language in a conversational manner. Frameworks and platforms such as Dialogflow or Microsoft Bot Framework facilitate the development of chatbots by providing essential tools for understanding user intents. These chatbots can handle customer inquiries efficiently, improving service quality and freeing up human agents for more complex queries.
