100% private document Q&A powered by local LLMs

open sourceupdated Aug 16, 2026

PrivateGPT enables fully private document interaction using GPT-powered RAG without any data leaving your machine. Ingest documents (PDF, DOCX, TXT, and more) and chat with them using local LLMs via Ollama or remote providers. Built on LlamaIndex with Qdrant vector storage. 57,200+ GitHub stars, Apache 2.0 licensed. The go-to solution for air-gapped environments, regulated industries, and anyone who needs document Q&A without cloud data exposure.

A detailed review by the aicoolies team — click to read

PrivateGPT was one of the first projects to demonstrate that document Q&A could work entirely offline, without sending any data to external APIs. The architecture ingests documents through a parsing pipeline, chunks and embeds them into a local vector store, and uses a local LLM to answer questions with retrieved context. Every component — parsing, embedding, storage, and generation — runs on your hardware.

The current version is built on LlamaIndex for the RAG pipeline and supports Ollama for local model inference, with Qdrant as the default vector database. A REST API enables programmatic document management and querying, while the built-in web UI provides a ChatGPT-like interface for interactive use. The system supports both private mode (fully offline) and external mode (using cloud LLMs) for flexibility.

With 57,200+ GitHub stars, PrivateGPT is one of the most popular open-source AI projects globally. It is Apache 2.0 licensed with 97+ contributors. The project is particularly adopted in healthcare, legal, financial, and government sectors where data sovereignty requirements prevent cloud-based AI tools. Compared to AnythingLLM which offers a broader feature set, PrivateGPT is more focused on the pure privacy-first document Q&A use case with simpler deployment.
