    <abstract>This paper describes our system submitted to the AbjadGenEval Shared Task at ArabicNLP 2026, which focuses on binary classification of human-written versus machine-generated text in low-resource languages. We participated in two independent subtasks targeting Arabic and Urdu news and literary texts. Our approach relies exclusively on fine-tuning XLM-RoBERTa, a multilingual Transformer-based model, under carefully controlled training and preprocessing settings. While the same model architecture was used for both subtasks, language-specific data handling strategies were applied based on empirical observations. The proposed system achieved first place in the Urdu subtask and third place in the Arabic subtask according to the official evaluation. These results demonstrate that multilingual pretrained models can serve as strong and reliable systems for AI-generated text detection across diverse languages.</abstract>
