About This Project
Tijori is a high-performance family card wallet and security vault designed to store credit/debit cards completely offline. It utilizes client-side zero-knowledge cryptography using the Web Crypto API to derive AES-GCM encryption keys directly from the user's master PIN, securing card details on-device within IndexedDB. The application is integrated with a secure server-side Gemini 2.5 Flash chatbot with Google Search Grounding to evaluate real-time bank offers, benefit devaluations, and lounge criteria, providing users with a comprehensive overview of limits, credit utilization metrics, and family member filters.
