🌌 Bugs are evident™ - MATRIX️
🚧 This project is under active development!
📢 We welcome your feedback and contributions.

NodeJS LTS is supported

🛠️ Built on NodeJs version

v24.14.1

📝 Description

A Linux compatible version of OneNote.

Features

P3X OneNote Linux is an independent browser window for the online OneNote, so you can use it without cluttering your browser.

Core highlights:

• Runs in its own process, independent from any browser
• System tray support — close the window and keep it running in the background
• Cached data for faster startup compared to opening a new browser tab each time
• Supports both corporate and personal Microsoft accounts
• Multiple account tabs — sign into multiple accounts simultaneously, each in its own isolated session. Tab labels automatically show the account email after login.
• Auto-updates when a new version is available
• Access other Microsoft online applications as well (dedicated purpose is OneNote)

Detailed Features

User interface:

• Press ALT to access the menu
• Desktop menu system integration
• Window zoom functionality
• Tab bar — add, switch, and close account tabs. Click + to add a Personal or Corporate tab. Each tab shows the logged-in account email.
• Tab drag-and-drop reordering — drag tabs left/right to rearrange them, order persists across restarts
• Tab renaming — right-click a tab to set a custom label (e.g. "Work", "Personal")
• Tab pinning — right-click a tab to pin it, preventing accidental closure
• Restore closed tabs — accidentally closed a tab? Use Action > Restore last closed tab to bring it back with the same login session (keeps up to 10 in history)
• Per-tab zoom — each tab remembers its own zoom level independently
• Dark mode (non-official workaround — may have minor inconsistencies since it is not directly supported by Microsoft)
• Dark mode follow system — automatically switches dark mode on/off when your OS theme changes (Settings > Dark mode > Follow system)
• Launch minimized with the --minimized argument

Navigation and clipboard:

• Bottom bar displays the current URL — click it to copy to clipboard
• Edit menu includes "Copy this location to the clipboard" option
• Remembers the last opened notebook (to the extent permitted by Online OneNote)

Settings (Menu > Settings):

• Close to the tray — when checked, minimizes to tray instead of exiting; when unchecked, closes completely on quit
• Proxy settings — configurable through the settings menu

Other:

• Granular session cleaner — clear cookies, cache, or everything for all tabs or just the current tab (P3X OneNote menu > Clear data and restart)
• Multi-monitor safety — if you disconnect a monitor and the window would appear off-screen, it automatically centers on the primary display
• Bookmark folders — organize bookmarks into nested folders using / separator (e.g. Work/Projects). Folders appear as submenus with 📁 icons in the Bookmarks menu.
• Bookmark manager — full dialog to search, inline-edit, and delete bookmarks (Bookmarks > Manage bookmarks)
• Bookmark import/export — export bookmarks to JSON and import from JSON file (Bookmarks menu)
• Corporate home menu item — note: without a corporate login, debugging this feature is not possible. If issues arise, providing login details may help with troubleshooting.
• Language: The language selector in P3X OneNote only controls the Electron app UI (menus, dialogs, buttons). To change the OneNote web content language, you must update your language in your Microsoft account profile. Translations are community-driven:
  • Translation resources on GitHub
  • Available languages: Afrikaans, العربية (Arabic), বাংলা (Bengali), Català (Catalan), Čeština (Czech), Dansk (Danish), Deutsch (German), Ελληνικά (Greek), English, Español (Spanish), Suomi (Finnish), Français (French), עברית (Hebrew), Magyar (Hungarian), Italiano (Italian), 日本語 (Japanese), 한국어 (Korean), Norsk (Norwegian), Nederlands (Dutch), Polski (Polish), Português (Portuguese), Română (Romanian), Русский (Russian), Српски (Serbian), Svenska (Swedish), Türkçe (Turkish), Українська (Ukrainian), Tiếng Việt (Vietnamese), 简体中文 (Simplified Chinese), 繁體中文 (Traditional Chinese)
• Single instance enforced — launching the app again brings the existing window to the foreground

Option	Description
Rename tab	Set a custom label for the tab

Removing quarantine on downloaded files:
