Chat Bot is defined as a program that simulates a conversation with a person by providing automatic responses when interacting with the person. Today, many well-known companies have already implemented chat bots in certain areas of their companies, with the aim of helping to avoid saturating those responsible for Social Media in companies (or Community Managers), as they are responsible for responding more obvious, simple and pre-established questions of the visiting or interested users, leaving the most particular or necessary cases to be solved by people. Many times, users do not notice the difference and believe that at all times they were assisted by the same person. We develop 3 kind of chatbots: 1) For more information, as a customer service support. 2) To reach more sales. 3) Integration with databases in Spreadsheets for more advance chatbots.
