About NoteDiscovery

NoteDiscovery is a self-hosted note-taking application aimed at people who want full control of their knowledge base. You write, organize, and search notes through a modern web interface, while the notes themselves are plain Markdown files stored on your server. It is released under the MIT license.

The README contrasts it with commercial tools such as Notion, Evernote, and Obsidian Sync, emphasizing no subscription, data kept on your own server, and no lock-in because of plain files. All browser libraries are served locally, so the app and its shared links also work on air-gapped networks, and simple password protection can be turned on for self-hosted deployments.

It is built with Python and FastAPI plus a JavaScript front end and is deployed with Docker. It suits privacy-conscious users, developers who prefer Markdown, knowledge workers building a personal wiki or second brain, and small teams wanting a straightforward self-hosted alternative.
