Private AI at Home: A RAG-Powered Secure Chatbot for Everyday Help

SMRTR summary

A developer created a secure, AI-powered family chatbot using Spring AI that runs entirely on personal home infrastructure to protect privacy. The system uses retrieval-augmented generation (RAG) to answer everyday questions by searching through local family documents, running smoothly on modest hardware like old laptops with just 8GB RAM. The chatbot operates across multiple devices via home Wi-Fi and supports voice input, making it accessible for non-technical family members while keeping sensitive data completely private.
