Helix — AI Digital Identity System

HELIX is an AI-powered Digital Identity & Knowledge Graph that transforms scattered academic and professional documents into a structured, searchable, and evidence-backed representation of a student's growth. Instead of simply storing files, HELIX understands uploaded content, automatically categorizes information, discovers relationships across experiences, visualizes growth through a digital journey timeline, and enables natural-language retrieval using Retrieval-Augmented Generation (RAG).

KEY DESIGN DECISIONS • AI is responsible for information extraction and categorization, while verifiability, relationship depth, and path coherence are computed using deterministic algorithms for transparency and consistency. • Classification, Verifiability, Relationship Depth, and Coherence are evaluated independently instead of being combined into a single opaque score. • Semantic search powered by vector embeddings and Retrieval-Augmented Generation (RAG) ensures responses are grounded in uploaded evidence rather than generated assumptions. • Original documents remain preserved in their native format and are always accessible. • The modular architecture allows document uploads to function independently, while GitHub and Telegram integrations remain optional extensions. DEPLOYMENT INFORMATION Frontend: Vercel Backend: Render Database: Supabase (PostgreSQL + pgvector) Note: The backend is deployed on Render's free tier. After periods of inactivity, the first API request may take approximately 30–60 seconds while the service resumes. Subsequent requests respond normally.
