NoteDiscovery
Your Self-Hosted Knowledge Base
NoteDiscovery is a self-hosted knowledge base application that stores notes as plain Markdown files in folders on your own server, keeping data under your control and avoiding proprietary databases. It supports wikilinks, smart search, tag filtering, an outline panel, card view, and an interactive graph view for navigating and connecting notes.
The editor includes live preview, LaTeX math via MathJax, Mermaid diagrams, code highlighting, an embedded drawing editor with autosave, image support, YAML frontmatter tags, custom templates with placeholders, themes, HTML export, and a plugin system. It offers an MCP server for AI assistant integration with tools such as Claude and Cursor, plus optional password protection, public sharing links, multiple interface languages, and PWA installation on desktop or mobile.
NoteDiscovery is aimed at individuals and self-hosters who want to run their own Markdown-based knowledge base, including those migrating from Obsidian vaults. It is free and open source under the MIT license, with no paid tiers or accounts; deployment is available through Docker or a one-click hosted option, and a daily-resetting live demo is provided.
