DocMason

DocMason is a special application designed to help you research deeply into your private work files. It works by turning your office documents like presentations, spreadsheets, PDFs, and emails into a personal knowledge base that stays on your computer. Unlike other AI tools that just turn everything into plain text, DocMason keeps the original structure and details of your documents. This helps AI agents understand the information better and makes sure that any answers you get can be traced back to where they came from in your files.

Benefits

DocMason is a privacy-first tool because it works entirely on your computer. Your files, your data, and your knowledge base never leave your local folders. It doesn't send any of your document content or questions over the internet. All the AI processing happens on your machine using an AI agent you choose, and DocMason itself doesn't make any calls to external AI models. This means your work information stays secure and private.

Use Cases

You can start using DocMason by placing your work files into a specific folder. For larger amounts of documents, you can prepare entire folders. DocMason will then set up a local system and process your documents to build the knowledge base. Once this is done, you can ask complex research questions. The answers you receive will clearly show which file and even which part of the file the information came from, so you can easily check it against the original document.

DocMason can handle many types of files, including Office documents (.pptx, .docx, .xlsx), PDFs, and text files like .md and .eml. It uses local tools to read these files accurately, keeping their structure and layout intact for better analysis.

Additional Information

DocMason is currently in its early stages, called alpha. It offers important features like automatically updating when you add or change files, checking data before saving it, understanding sources deeply, and providing clear links back to the original information. It works with AI assistants like Codex on macOS, Claude Code, and GitHub Copilot. The developers aim for DocMason to be a trustworthy, private, and open AI assistant for professionals who need to be sure about the source of their information.
