Zero for Outlook by Luke's Labs

Transform Outlook on the web into a keyboard-driven powerhouse. Zero for Outlook brings you lightning-fast shortcuts, Vim-style navigation, and intelligent productivity features, all designed to help you reach Inbox Zero faster.

Why Install Zero for Outlook?

Command Bar Press Cmd+K (or your custom shortcut) to instantly access every feature. Search and execute commands faster than you can click, snooze emails, navigate folders, toggle settings, or jump to Calendar and To Do in seconds.

Vim-Style Navigation Navigate like a pro with h/j/k/l keys. Move seamlessly between folders and messages, select multiple emails with Shift+J/K, and keep your hands on the keyboard where they belong.

Smart Snooze Overlay Press 'S' on any message to open an elegant snooze menu. Choose from preset times (Later today, Tomorrow, This weekend, Next week) or pick a custom date, all with keyboard navigation.

Undo Archive Shortcut Accidentally archived an important email? Press your configured undo shortcut (like Ctrl+Z) to instantly reverse the action, no more hunting for that fleeting Undo button.

AI Email Summaries (Optional) Connect your Google Gemini API key to generate instant summaries of lengthy emails, highlighting only what matters.

Customizable Shortcuts Create your own keyboard shortcuts for any action in Outlook. Use the visual element picker to click any button with a keystroke, fully tailored to your workflow.

Dark Mode & Clean UI Enable dark mode for overlays and extension UI. Optionally hide Outlook's top navigation for a distraction-free, focused inbox experience.

Inbox Zero Celebration (Beta) Get a satisfying celebration overlay when you finally reach that glorious empty inbox.
