PeerCraft – A Community-Driven Peer-to-Peer Skill Exchange Learning Platform

Digital learning platforms have significantly expanded access to education; however, many systems continue to follow instructor-centric and subscription-based models that restrict participation and personalization. In response, recent research has explored peer-to-peer learning environments in which users collaboratively exchange knowledge and practical skills. Studies in collaborative education, educational recommender systems, and online communities propose mechanisms such as partner-matching algorithms, communication support, and reputation-based trust evaluation to improve engagement and learning effectiveness. Nevertheless, existing approaches typically address these components independently, leading to challenges in credibility assurance, scalability, and sustained interaction. This paper presents a comprehensive survey of peer learning and skill-sharing platforms by analyzing their methodologies, advantages, and limitations reported in prior research. Based on the comparative analysis, the study identifies the need for an integrated framework that combines intelligent matching, interaction support, and reliability assessment to enable structured and accessible knowledge exchange.
