Software that simulates human conversations is known as a chatbot. Early chatbots were built based on frequently asked questions (FAQ) and gradually evolved to use conversational AI tools to give the feel of a natural language conversation. Chatbots are often used to provide information in a timely manner without distinguishing business hours or days of the week. In online diagnostic instruments, answered by thousands of students in a limited period of time, it is useful for answering questions related to access, navigation, question and answer display, as well as sending and obtaining the result.

The use case presented in this paper is the chatbot implemented for the online diagnostic instrument TICómetro applied during August and September 2024 to 42 thousand students entering UNAM. The TICómetro was developed by the Coordination of Technologies for Education, now the Directorate of Innovation of Technologies for Education (DITE), of the General Directorate of Computing and Information and Communication Technologies (DGTIC) of the National Autonomous University of Mexico (UNAM), with the aim of providing UNAM schools with information on access and skills in the use of Information and Communication Technologies (ICT) of their students.
