Noteworthy is currently in development! I work on Noteworthy in my free time, so progress comes in bursts. I hope to have a public beta available for release before January 2022.

Noteworthy (

A free, open-source, local-first Markdown editor built with ProseMirror.

  • Works directly with your local files, entirely offline.
  • Write your notes in Markdown, with syntax extensions like citations and block directives.
  • Build your own personal wiki with bidirectional links.
  • Excellent math support — seamlessly transition between source and rendered math, thanks to KaTeX and prosemirror-math.

Building Noteworthy

Noteworthy is NOT quite ready for use. However, you can follow these instructions if you really wish to run it.

git clone --recurse-submodules
cd noteworthy
npm install
npm run dist

After building, look in the /dist folder for an executable.


  • Thanks to Marijn Haverbeke for developing ProseMirror!
  • Thanks to Hendrik Erz for keeping Zettlr open source! When I started developing Noteworthy, I had no clue how to set up an Electron app or responsibly interact with the user's file system from Node, and the Zettlr source was a great reference.
  • Thanks to Microsoft for keeping VS Code open source! I learned a lot by reading the source of the VS Code tree viewer and plugin system.
  • Thanks to Fabio Spampinato for releasing the source to an early version Notable!
