Development of an AI-Based Smart Device for Quran Memorization Using Spaced Repetition Technique

This paper presents the development of an intelligent Quran memorization device that integrates Artificial Intelligence (AI) and the spaced repetition technique to strengthen long-term memory of Quranic verses. The system, named Sahib Al-Quran, was designed as a portable embedded device using a Raspberry Pi Zero 2 W as the main processor, a ReSpeaker 2-Mics HAT V2 for voice input and output, a UPS Lite battery for wireless operation and a 2.13-inch e-paper display for low-power visual output. The device employs an AI-based repetition schedule that reminds users when to review verses and provides real-time feedback through speech recognition. Beyond the hardware development, a quantitative experimental study was conducted using an SPSS t-test to compare memorization performance between a control group and an experimental group that used the device. The results revealed that the experimental group achieved significantly higher memorization scores, suggesting that integrating AI and spaced repetition into a physical learning aid can effectively improve Quran memorization and retention. This study highlights how modern technology can enhance Islamic educational practices while preserving traditional values.
