We explore AI companion usage patterns on the Chaoxing (Superstar) Learning Platform using survey data from 75 university students. Using a three-tier EDA framework (univariate description, bivariate correlation, and multivariate exploration), we examine usage behaviors (frequency, duration, depth), usage purposes (seven categories), demographic differences, and user perceptions. Key findings reveal a significant positive correlation between usage duration and depth (Spearman ρ = 0.325, p < 0.01), suggesting a learning curve effect. Usage purposes are significantly associated with behavioral depth: students using AI for assignments (p = 0.005), emotional support (p = 0.011), and AI Q&A (p = 0.023) demonstrate deeper engagement. The strongest purpose co-occurrence is between assignments and instructor requirements (Jaccard = 0.672). In addition, demographic variables (gender, grade, major) show no significant association with usage behavior, with similar usage patterns across groups. User perception analysis reveals ‘convenient’ as the dominant keyword (n = 22), surpassing ‘useful’ (n = 10). Overall, usage correlates with depth, purposes differentiate depth, and convenience dominates perceptions; findings are relevant to platform design.Exploratory data analysis (EDA),AI companion,Chaoxing platform,Usage behavior,Learning analytics
