NoteDiscovery

NoteDiscovery is a lightweight, self-hosted markdown knowledge base that keeps you in full control of your notes. Write and organise your notes as plain markdown files, with fast full-text search, backlinks and an interactive graph view of how your notes connect.

Highlights

• Plain markdown storage – no proprietary formats, no lock-in; notes are just files you can back up or edit externally.
• Fast search & discovery – instant full-text search, wikilinks, backlinks and an interactive graph view.
• Rich previews – LaTeX/MathJax equations, Mermaid diagrams, syntax-highlighted code and callouts.
• Themes & plugins – multiple built-in themes and an extensible plugin system.
• Export & print – export notes as standalone HTML or print them.
• Optional authentication – simple password protection for self-hosted deployments.
• No CDN required – all browser libraries are served locally, so it works on private or air-gapped networks.
• AI assistant ready – an optional MCP server integrates with tools such as Claude and Cursor.
• Responsive – works across desktop, tablet and mobile.

Cloudron notes

• Notes and attachments persist in /app/data/data.
• Plugins persist in /app/data/plugins.
• Authentication is disabled by default; enable it in /app/data/config.yaml under authentication.enabled.
