The primary objective of this study is to identify the experiences and challenges encountered by Grade 11 students in using artificial intelligence (AI) applications for academic writing, as well as their coping mechanisms. This study employed a qualitative research approach and a narrative inquiry design to determine the general findings. It focused on nine (9) Grade 11 students—three from each academic strand: Science, Technology, Engineering, and Mathematics (STEM); Accountancy, Business, and Management (ABM); and Humanities and Social Sciences (HUMSS)—for the school year 2024–2025. A semi-structured interview guide was used to collect data, which was analyzed using Colaizzi’s method. The results revealed that most students became overly reliant on AI applications for academic writing. While they acknowledged the convenience, reliability, and accuracy of information provided by AI chatbots, concerns about overdependence were noted. Additionally, students reported that AI-generated information was easy to access and direct when prompted. The study also highlighted various coping mechanisms employed by students, such as enriching the AI-generated content, paraphrasing and summarizing, and using AI tools to develop their writing skills. The findings suggest that while AI applications can support the learning process and enhance knowledge acquisition, their use throughout the entire writing process may affect students' ability to formulate original ideas, apply analytical skills, and demonstrate creativity. Overall, the use of AI applications can aid students in their academic journey, but it must be balanced with adherence to ethical practices at all times.
