In the digital era, Artificial Intelligence is increasingly developing. In recent years, one of the promising development in this field is ChatGPT which has sparked considerable interest. ChatGPT is a language model developed by OpenAI that allows people to interact with a computer in a more natural and conversational way. It offers students and educators personalized learning experiences Linked to ChatGPt open AI API. Therefore, we present in this paper a virtual tutor, named NAJEH, integrated into the student engagement portal and mobile application (MYU) and have access to the Student Information System (SIS) and Learning Management System (LMS) of the Honoris United Universities<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sup><sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sup>https://honoris.net/, which includes 6 institutions in Tunisia. Around five thousand students from the Université Centrale had the learning experience with NAJEH. A survey was carried out in order to explore students satisfaction and acceptance of NAJEH. Thus, with a 76% response rate, results show that more than 80 % of students find this chatbot tutor very useful, easy and use it at least once a day. As perspective, we propose to investigate on the impact of these interactions on the students' academic performance and teaching efficiency. In fact, an in-depth study requires more data available over a longer period, even several years.
