Challenges include restricted access to premium capabilities, the intricacy of advanced ideas, internet connectivity problems, and device limits were recognized as impediments to optimal tool utilization. Notwithstanding these challenges, the tool significantly enhanced writing precision, assisting students in generating clearer and more logical arguing compositions. The study emphasizes the significance of including AI writing tools as supplementary resources in vocational education, while warning against excessive reliance and highlighting the necessity for instructional oversight. The study's limitations encompass its brief duration, cultural distinctiveness, and dependence on a singular version of the tool, potentially impacting generalizability. Subsequent study ought to investigate longitudinal impacts, cross-cultural relevance, and the incorporation of new AI technologies to enhance writing education in vocational EFL settings.]]>
