The use of chatbots in a variety of businesses is becoming more and more recurrent due to the scalability of customer service and the generation of automatic purchase processes. This project develops a chatbot system called Chatty that uses NLP to receive customer orders through an instant messaging application for the Snap eats delivery platform. The implementation of the chatbot achieved a significant percentage increase in the number of orders during the period in which it was measured. In addition to receiving positive ratings from users regarding ease of use. Using NLP in a chatbot for communication with customers is unusual due to the complexity and lack of control over the conversation; however, by applying a defined data flow, such complexity is reduced since the user is addressed without the need to use predetermined forms, creating a more fluid interaction. The NLP engine used for this project is GPT-3, which is a very powerful language generator model created by the company OpenAI.
