Let’s review. What is a chatbot?

Chatbots are computer programs that mimic conversation with people through the use of artificial intelligence.

In a nutshell, when someone types in a message, the bot responds with the right reply.

Out of the thousands of chatbots that exist today, most are messenger apps designed to communicate with customers. They work with Natural Processing Language (NLP) systems which translate everyday language into a form that the bot can understand and learn new interactions from.

Through the help of that technology, bots now hold endless possibilities. You can use them to read everyday news, get the weather, transfer money, buy your favorite items, schedule a meeting, or even get service assistance. And all from the convenience of your favorite messenger app.
