Built on rigorous psychological research and advanced matching algorithms
Carefully designed 66 values assessment questions covering 6 core dimensions: life philosophy, social perspectives, interpersonal relationships, personal growth, emotional attitudes, and lifestyle. Creates a comprehensive values profile.
The assessment covers six core dimensions: Life Philosophy, Social Perspectives, Interpersonal Relationships, Personal Growth, Emotional Attitudes, and Lifestyle. Each dimension is analyzed independently to generate a comprehensive values radar chart.
We use Cosine Similarity to calculate the angle between two people's values vectors, precisely quantifying the degree of values alignment and ensuring scientifically reliable matching results.
Research shows that value alignment is the #1 predictor of long-term relationship success. Couples with shared values report 67% higher satisfaction, providing a solid theoretical foundation for our matching algorithm.
Combined with the Big Five personality model (Openness, Conscientiousness, Extraversion, Agreeableness, Neuroticism) to further optimize matching precision from a personality perspective.
All AI computation is performed on our own servers. User data is never shared with any third-party AI services, ensuring maximum privacy protection while maintaining matching quality.
