Postgraduate students in developing nations, such as South Africa, are increasingly leveraging artificial intelligence tools like ChatGPT to elevate their academic success in the era of the fourth industrial revolution. This study aims to explore postgraduate students' perceptions of the benefits associated with the utilisation of artificial intelligence tools, with a specific focus on ChatGPT, in their academic success in South Africa’s historically disadvantaged universities. Employing a qualitative approach, the study aims to gain a deeper understanding of postgraduate views on this subject. The sample size comprised 10 postgraduate students pursuing master's degrees within the two selected South Africa’s historically disadvantaged universities, selected through purposive sampling. Semi-structured interviews were conducted to gather insights from the postgraduate students. Thematic analysis was employed to analyse the collected data. The study's findings shed light on the significant advantages of incorporating ChatGPT in students' academic journey with special focus on research success. The study found that ChatGPT proves beneficial for postgraduate students, with some utilising the AI tool to refine their research topics before submission to their supervisors. Moreover, ChatGPT assists postgraduate students in identifying grammatical errors and paraphrasing their academic writing, contributing to the enhancement of their writing skills. In light of these findings, the study recommends the immediate development of an innovative AI ethical use policy in South Africa’s historically disadvantaged universities. This policy should emphasise ethical guidelines for postgraduate students when utilising AI tools, such as ChatGPT to ensure responsible and effective integration into their academic success.
