SoulCode
SoulCode is a mobile application that compiles self-assessed personality dimensions (MBTI), attachment style, and personal values into a 14-dimensional numeric signature, effectively modeling a user's 'soul' as a structured data object. It then finds and ranks potential connections based on a weighted resonance score that combines cosine similarity of the personality/attachment/value vectors with semantic affinity of shared interests. An AI chatbot explains match results in plain language. The app offers three connection paths: sharing a personal link to check resonance with specific friends, a curated daily discovery feed (limited to 10 new candidates on the free tier to avoid endless swiping), and mutual opt-in matching that unlocks chat. Premium users can regenerate their soul code monthly to track personal growth, with the app visualizing how the signature evolves over time. SoulCode supports English, Chinese, Japanese, Korean, and Spanish, and is currently available exclusively on the Apple App Store.
