Interact privately with your documents using the power of LLMs.
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.
Verification snapshot
Release history
PrivateGPT 0.6.2, released on August 8, 2024, brings significant enhancements to its Docker setup for easier deployment and management. Key improvements include a simplified cold-start with better Docker Compose integration, environment-specific profiles for CPU, CUDA, and MacOS, and pre-built Docker Hub images for faster deployment. This release also introduces support for Google Gemini LLMs and Embeddings, and sets Llama 3.1 as the default LLM for Ollama and Llamacpp local setups.

What we love
Watch out for
What is PrivateGPT and how does it ensure privacy?
PrivateGPT is an open-source project that allows you to interact with your documents using large language models (LLMs) entirely locally. It ensures privacy by performing all data processing, including embedding generation, vector storage, and LLM inference, on your own machine. No data or queries are ever sent to external cloud services or third-party APIs.
What kind of documents can I use with PrivateGPT?
PrivateGPT supports a wide range of document types, including common formats like PDF, TXT, DOCX, Markdown, CSV, and more. The ingestion pipeline processes these documents, extracts their text content, and converts them into a format suitable for local indexing and retrieval.
Do I need a powerful computer to run PrivateGPT?
The performance of PrivateGPT is highly dependent on your local hardware, particularly for running the LLMs and embedding models. While it can run on most modern machines, a dedicated GPU with sufficient VRAM (e.g., 8GB+) and a good CPU are recommended for optimal speed and to handle larger LLMs. It also utilizes quantized models (like GGUF) to reduce resource requirements.
Is PrivateGPT truly free to use?
Yes, PrivateGPT is an open-source project released under an MIT license, making it completely free to use, modify, and distribute. The only costs you might incur are for your local hardware, electricity, and potentially any proprietary LLM licenses you might choose to integrate (though it primarily leverages open-source models).
