This research addresses the barriers children face in accessing quality tennis instruction, particularly those with special needs who require personalized learning approaches. Traditional programs often lack individualized teaching methods and accessibility, with approximately 60% of children dropping out of organized sports by age 13 due to cost, limited access, and engagement challenges. To overcome these issues, the proposed AI-powered tennis training application leverages OpenAI’s ChatGPT API, Firebase cloud infrastructure, and progressive level systems to deliver personalized, narrative-driven training experiences [1]. Its three core systems include AI content generation for individualized exercise descriptions, Firebase authentication for secure user management, and real-time progress tracking with visual feedback [2]
