About PrivateGPT
PrivateGPT is a robust, open-source project dedicated to enabling entirely private and local interactions with user documents using large language models (LLMs). It orchestrates a sophisticated Retrieval Augmented Generation (RAG) architecture, allowing users to query their personal or corporate data without ever transmitting sensitive information to external cloud services or third-party LLM APIs. The technical foundation relies on a modular stack that typically includes locally hosted LLMs—often optimized through quantization (e.g., GGML, GGUF) for efficient execution on consumer-grade hardware—alongside local embedding models, such as `sentence-transformers`, to convert textual content into vector representations. These embeddings are then stored in a local vector database, commonly ChromaDB, facilitating rapid semantic search. The platform supports ingestion of diverse document formats like PDFs, DOCX, and TXT, which are chunked, embedded, and indexed on the user's machine. When a query is made, PrivateGPT retrieves the most relevant document snippets locally, provides them as context to the chosen local LLM, and generates a precise, contextually grounded answer. This architecture is paramount for ensuring unparalleled data privacy, compliance, and eliminating data leakage risks, making it an ideal solution for handling highly confidential information. It further offers a flexible RESTful API for developers and an intuitive web UI for end-users.
