PDF Pals

About PDF Pals

PDF Pals is a native macOS app for chatting with PDF documents that keeps the documents on the machine. The category is crowded with web apps that require uploading a file to a hosted service where it is chunked into a cloud vector database, and PDF Pals is built as the direct negation of that: documents are never uploaded, no cloud vector database is involved, embeddings and chat history live in a local SQLite file you can back up yourself, and there is no in-app analytics. The model access is bring-your-own-key across OpenAI, Azure OpenAI Service and OpenRouter, with the key stored in the Apple Keychain, and a rented key is offered for people who do not want to manage one. Being native rather than Electron is a stated design goal — the vendor's phrasing is that it is not another 500MB Electron app — and it shows in the practical limits: there is no file size cap, and multiple PDFs can be interrogated at once. A built-in OCR engine handles scanned PDFs and complex forms, which is what makes it usable on the archival documents that defeat text-extraction-only tools. The site publishes role-specific guidance for developers, academic researchers, product managers, legal professionals and HR, and reports 575 customers. Requires macOS Ventura 13 or later.
