What is ChatPDFLocal?

ChatPDFLocal offers a secure and efficient way to interact with PDF documents directly on a Mac. This native macOS application prioritizes user privacy by ensuring all data, including the PDFs and chat history, remains stored locally on the user's machine, never uploaded to the cloud. It provides access to a wide range of powerful Large Language Models (LLMs) such as ChatGPT, Gemini, Llama 4, DeepSeek, and Claude, allowing users to leverage their preferred AI through their own API keys for enhanced analysis and understanding of document content.

The tool supports chatting with multiple PDFs simultaneously in real-time, facilitating comprehensive information retrieval without lengthy waits. It incorporates a built-in local vector database and Retrieval-Augmented Generation (RAG) technology to improve the accuracy and relevance of AI-generated responses. Furthermore, integrated Optical Character Recognition (OCR) capabilities enable the extraction of text and information from visual elements within the PDFs, adding another layer of data processing. The application is designed for a fast and seamless user experience within the macOS environment.
