NoteDiscovery

NoteDiscovery is a self-hosted Zettelkasten-style knowledge base for people who think in linked notes rather than databases. It is MIT-licensed, built with JavaScript and Python (FastAPI), and stores content as plain Markdown files in folders — no vendor lock-in. The feature set (wikilinks, graph view, drawing editor) is closer to Obsidian than to Notion, and it targets personal wikis and "second brain" workflows.

NoteDiscovery ships a built-in Model Context Protocol (MCP) server that exposes your notes to AI agents. With a one-line config, assistants like Claude Desktop and Cursor can search, create, edit, tag, and reorganize notes directly inside your knowledge base. It's positioned as an "AI Assistant Ready" feature rather than a built-in chatbot — you bring your own agent.

It includes wikilinks/backlinks, a graph view, outline panel, favorites, and a quick switcher, plus Mermaid diagrams and LaTeX/MathJax rendering for technical notes. There's also an in-browser drawing editor that saves sketches as drawing-*.png files alongside the note (autosave, shapes, eraser, eyedropper, undo/redo), and a plugin system for extensions.

The quickstart is a single docker run with one bind mount for ./data:/app/data and port 8000 exposed. It also publishes Docker Compose files and a PikaPods one-click deploy option for users who don't want to run their own server. Optional password auth, PWA install, and a plugin system are all configurable without rebuilding the image.
