For upper secondary education, one of the main functions of guidance teachers is to provide information services for tertiary education for students. However, from the preliminary study of the case study school, it was found that, a ratio between the number of guidance teachers and students was not suitable enough to provide services. Moreover, information service was usually limited only during the guidance study period. The objective of this research is to use digital technology to reduce the burden of guidance teachers by developing a chat bot system that can provide service related to higher education information. Students can inquire through the chat bot system at all times that they connect to the internet. From the systematic satisfaction evaluation of the sample of 20 students, it was found that the average satisfaction was at a high level. In addition, the developed chat bot system can be a prototype for further development or dissemination to use for guidance in other schools or in universities.
