Nowadays, many applications are using chatbots and virtual assistants. IT teams to end consumers utilize new chat-based techniques to interact with computer systems. There are also many intelligent chatbot APIs that enable you to build your own AI chat-based programs.

Before diving into chatbot APIs, what exactly do we mean by chatbots? Why are they used, and in what applications?

What Are Chatbots?

In technical language, chatbot software uses Artificial Intelligence (AI) to interact with any user naturally. Companies often utilize such AI-driven messaging in websites, help centers, and mobile interfaces. For instance, say you need to buy new shoes, so you visit a retail store’s website. Here, a chatbot could help you select the shoes of your choice in a conversational format. Overall, chatbot software is well-programmed to perform tasks automatically using natural language inputs.

Why Should You Use Chatbots?

Chatbots are advanced options that help create better communication between human and computer systems. In a way, you could say chatbots are advancing the old question-answer system. Since chatbots use Natural Language Processing (NLP), they enhance user experience and engagement for end-user enterprise applications. Chatbots could also reduce a company’s customer service costs. The vital thing to realize is that chatbots require human involvement to be trained.

How Do Chatbots Work?

Getting a chatbot to work is a relatively complex procedure in which there are two main tasks. The first task is to understand the user request, and the second task is to respond to user requests appropriately. Developing chatbot applications will require a few different strategies, like artificial intelligence, semantic understanding, and machine learning. To create a chatbot on a preexisting chat interface, you will likely need to plug into that network’s chatbot API.
