What is NoteDiscovery?

NoteDiscovery is a web app for writing, organizing and finding Markdown notes on your own server. It shows how notes connect in an interactive graph, renders LaTeX math, and can be extended with plugins. Notes stay as local Markdown files, which suits people who want complete control of their data and developers who prefer plain text. It runs in one Docker container, and the interface is translated into 10 languages.

Good fit if

  • You want an Obsidian-like experience in the browser on your own server.
  • You want a quick setup with one container.

Look elsewhere if

  • You want a mature project with years of history: it first appeared in November 2025. Trilium Notes is long established.
  • You want an even simpler app without graphs: flatnotes.

Before you adopt it

NoteDiscovery is MIT-licensed and free. It is very young and mostly written by its creator, so features and storage details may still change.
