Molio

Molio is a personal knowledge operating system that turns scattered notes, books, PDFs, and web clippings into a structured, local knowledge base that your agents can read and build on. Core capabilities: • Import notes, Word documents, PDFs, web pages, and books in one place • Preserve original files and folder structure • Automatically build a wiki and knowledge graph • Link people, events, and concepts across sources • Let Claude Code, Codex, and other agents research and write from your material • Save agent outputs back into the knowledge base for future work. Everyone accumulates experience, methods, and professional expertise, but it often gets buried across notes, documents, and chat histories. Molio organizes these materials into a navigable map where connections are visible and retrieval is fast, so past work becomes a foundation rather than a forgotten archive. Each source stays traceable to its original text, which makes verification straightforward. Because the knowledge base is built around your own files and runs locally, your data stays on your computer throughout. Results from research, writing, and coding sessions flow back into the knowledge space, compounding over time. The project is open source under the MIT license, and the desktop app for Windows is free. Ideal for researchers, writers, students, historians, and consultants who work from large reading collections and want their notes to power daily work. Pre-built domain knowledge bases, such as Zizhi Tongjian and Shiji, can be imported to start immediately.
