The ability to comprehend reading material is a crucial skill for academic and professional success, yet many students struggle with it, negatively impacting their academic performance. This study aimed to assess the effectiveness of AI-based personalised reading platforms in improving reading comprehension among senior high school students. The study involved an experimental group of 43 students who used the platform and a control group of 42 students who did not. Pre- and post-test assessments were conducted using the Degrees of Reading Power (DRP) test, and an independent samples t-test was used for statistical analysis. The study found that the students who used the AI-based platform had significantly higher reading comprehension scores than those who did not, indicating that the platform effectively enhanced reading comprehension. Educators and administrators should consider incorporating AI-based personalised reading platforms into their teaching strategies to improve students' reading skills. Further research could investigate the long-term impact of these platforms.
