Cognitive Twin is an innovative application built for the MongoDB hackathon that models and queries personal thought patterns. It leverages MongoDB Atlas for secure data storage and advanced vector search capabilities. The system integrates Google Gemini AI to process embeddings and generate intelligent responses based on user data. A lightweight, real-time Node.js backend powers the seamless interaction between the user interface and the database. The project serves as an interactive AI-driven digital twin designed to understand and reflect user insights dynamically.
