Amidst growing mental health challenges and limited access to professional services, artificial intelligence (AI) has emerged as a potential support system for many, including medical students. This study aims to evaluate the use and perception of AI for psychological self-help within this demographic. A cross-sectional study was conducted via an online questionnaire between March and May 2025, encompassing 398 medical students in Morocco. Data regarding sociodemographics, AI usage for general and psychological purposes, and the boycott's impact were collected and analyzed. The cohort was predominantly female (73.1%), with a mean age of 21.34 (SD = 2.36). A significant proportion reported psychosomatic disorders (43%) or a prior psychiatric history (35.7%). AI tool adoption was near-universal (97.7%), with ChatGPT being the primary choice (91.5%). Notably, 61.8% of students utilized AI for psychological self-help. This specific use was significantly correlated with being female (p = 0.010) and having a history of psychosomatic disorders (p = 0.003), psychiatric conditions (p < 0.001), or OCD (p = 0.015). Students reporting psychological distress from the academic boycott also showed higher use for this purpose (p = 0.003). These findings demonstrate that AI is already a widely adopted tool for psychological self-help among medical students. This underscores the urgent need to harness its potential responsibly and establish guidelines to monitor its use effectively.
