Notion and other cloud note apps are convenient, but your notes end up locked inside someone else's database, reachable only through their app. NoteDiscovery works the opposite way: it stores every note as a plain Markdown file on a server you control, a bit like keeping your notes in labeled folders you own outright instead of renting a locker at someone else's storage facility — you can back it up with a simple copy command, or move it anywhere, any time. NoteDiscovery is a free, open-source (MIT) self-hosted knowledge base built around a folder of Markdown files, with no proprietary database format. It includes an interactive graph view for visualizing links between notes, a built-in drawing editor, LaTeX/MathJax support for equations, full-text search that works offline (including on air-gapped networks), multiple themes, and HTML export. Its standout 2026 feature is a built-in MCP (Model Context Protocol) server, so AI assistants like Claude Desktop and Cursor can search, create and organize notes directly, without manual copy-pasting.
