This research explores the development of an AI-powered journaling application designed to improve teen mental health by combining wellness journaling, AI-generated feedback, and trend analysis. The study investigates whether frequent journaling and AI-driven insights contribute to emotional awareness, stress management, and long-term mental well-being [10]. The application uses ChatGPT API to analyze journal entries, providing structured feedback and generating weekly mental health trend reports. Two experiments were conducted: one measuring pre- and post survey results and another comparing frequent vs. infrequent journaling. Results showed significant improvements in stress reduction and emotional expression among frequent journalers, validating AI-assisted journaling as a promising tool. However, challenges such as AI personalization, user engagement, and external influences require further refinement [11]. This research suggests that AI-powered journaling can serve as a valuable complement to traditional mental health resources, fostering self-awareness and proactive emotional management among teenagers[12].
