Kintsu AI – AI Digital Identity System

Kintsu AI is an AI-powered digital identity system that transforms uploaded certificates, resumes, project reports, transcripts, and portfolios into a searchable knowledge graph, digital timeline, and AI-generated identity card. Setup Backend: pip install -r requirements.txt Copy .env.example → .env Add a GROQ_API_KEY (Gemini and Cerebras are optional fallback providers) Run python main.py Frontend: cd frontend npm install npm run dev Register a new account and upload a few documents (certificates, resumes, project reports, etc.) to explore document categorization, semantic search, the knowledge graph, digital timeline, analytics, and the identity card. Architecture Classification is fully deterministic using keyword rules followed by multi-prototype embedding similarity. The LLM never controls application logic—it only explains classification decisions and proposes graph relationships. All LLM requests are routed through a resilient fallback chain (Groq → Gemini → Cerebras) with hard timeouts to keep the application responsive. Note No public deployment is available for this submission. Please run locally using the steps above. The repository README contains screenshots, architecture diagrams, and detailed implementation notes.
