Ruanyun is a small Chinese edtech company focused on AI-powered learning and assessment tools for K-12 students, headquartered in Nanchang, Jiangxi Province. The company operates two core platforms. SmartHomework uses OCR scanning devices to digitize students' paper-based homework, analyzes performance, identifies knowledge gaps, and delivers a personalized printed exercise book to each student within 24 hours, while giving teachers real-time insights. SmartExam delivers China's Academic Proficiency Test (APT), a government-mandated multi-subject exam required for high school graduation, providing the full stack including test content, certified testing centers, system management, and onsite support. Ruanyun claims to be the leading computer-based APT vendor across all 11 tested subjects in Jiangxi Province. Revenue comes from two channels: government and institutional contracts for SmartExam services, and consumer subscriptions and hardware sales on the SmartHomework platform, where free users are converted into paying subscribers over time. Ruanyun also sells smart hardware including its OCR scanning devices and a SmartHeadset for English practice. As of March 2025, roughly 15.15 million students across more than 20,000 schools use Ruanyun's platforms. Growth strategy centers on expanding SmartExam nationally as China pushes computer-based APT adoption, deepening subscriber conversion domestically, and an early-stage international push via HanLink, an AI-powered Chinese language learning platform launched in Saudi Arabia in May 2025. Ruanyun completed its Nasdaq IPO in April 2025, raising approximately $15M.
