Although peer feedback can promote active learning, reflective thinking, and evaluative judgment, inconsistencies and inaccuracies in student assessments often undermine its impact. This study proposes PeerReli-AI, an AI-supported peer feedback framework that integrates automated quiz administration, peer evaluation, and AI-generated formative guidance. A messaging-bot infrastructure was used to deliver quizzes and manage anonymous peer feedback, while the Gemini large language model generated context-aware feedback on students’ peer evaluations. The framework was implemented in an undergraduate Data Structures and Algorithms course across multiple iterative assessment cycles. Results from Hotelling’s T² tests and linear mixed-effects models demonstrate a significant reduction in discrepancies between peer and instructor evaluations over successive iterations when AI guidance was provided. Survey findings further indicate that students perceived the AI-generated feedback as engaging, useful, and supportive of their learning. Overall, the findings suggest that PeerReli-AI enhances the reliability and quality of peer feedback and offers a scalable approach for improving formative assessment practices in large higher education classrooms.
