Opus is a minimal note-taking application.

It aims to be a mix between a text-editor and code-editor. It reads and writes .note files from your native file system. This means it works well with tools like Dropbox for syncing files across your devices.

Much like a code-editor, Opus opens folders and allows you to edit the files inside. You can have multiple windows open, each with a different folder.

• 🖋 Editing: Supports rich text editing with all the features you'd expect.
• 📄 Uses Files: Uses tangible files in JSON format, not inaccessible databases.
• 🌙 Dark Mode: Includes a dark mode for late night writing.
• ⚙️ Customizable: The sidebar and footer can be hidden for a more focused experience.
• 📂 Multiple Projects: Opus supports opening multiple folders at once.
• ✨ Simple: Opus has only the features you need.

You can download the latest macOS binary from releases.

Alternatively, you can run Opus locally from the command line:

$ git clone https://github.com/pacocoursey/Opus.git
$ cd opus
$ npm install
$ npm start

• Find, replace, goto functionalities.
• Spellchecker, easily replace with suggestions via right-click.
• Window settings (position, size, dark mode, etc...) are remembered between sessions.
• Export notes to plain text, html, and markdown files.
• Automatically ask to update note contents if it is edited elsewhere.
• Document statistics shown in the footer (line count, word count, cursor position).

• Left: distractionless plain text writing application.
• Quill: The rich text editor that runs inside Opus.
