PDF Pals

PDF Pals is a powerful and secure native macOS application designed to revolutionize how you interact with your documents. It allows you to instantly chat with any PDF file directly on your Mac, eliminating the need to upload sensitive files to the cloud. Built for performance and privacy, PDF Pals is not another slow Electron app; it's a fast, responsive tool that keeps all your documents and data stored locally on your machine. This approach guarantees that your information remains confidential and secure, with API keys safely stored in the Apple Keychain.

The application stands out with its robust feature set, including the ability to chat with multiple PDFs simultaneously, making it incredibly efficient for cross-referencing information. It has no file size limits, so you can work with large and complex documents like extensive research papers, legal contracts, or technical manuals without any issues. With a powerful built-in OCR engine, PDF Pals can even handle scanned PDFs and complex forms, extracting text with high accuracy.

How to use PDF Pals

Getting started with PDF Pals is straightforward. First, download the application and install it on your Mac (requires macOS Ventura 13+). There's no account creation required. Simply open the app and drag and drop one or multiple PDF files into the window. The app will then index the documents locally. You'll need to provide your own API key from a supported provider. The app guides you through setting up API keys from services like OpenAI, Azure OpenAI, OpenRouter, Groq, Mistral, Perplexity, and even local models via Ollama. Once the API key is configured and the documents are indexed, you can start asking questions in the chat interface. The AI will provide answers based on the content of your PDFs, including page references for easy verification.
