OmniOutliner 5

By The Omni Group

Open the Mac App Store to buy and download apps.


This is OmniOutliner 5: a flexible, svelte, and focused app for creating, collecting, and organizing information and ideas. OmniOutliner Essentials is simple—everything you need to get started. Pro adds powerful features like smart columns, password protection, keyboard shortcuts, and plenty more. Try out both for free!

Use an outline to put structure on new ideas and stories, quickly rearrange a document’s flow, and construct beautiful document for sharing with built-in themes. But it’s way more than just an outlining tool—you’ve got multiple columns, smart checkboxes, pop-up lists, and a fantastically rich styles system at your disposal.

It’s perfect for drafting a simple to-do list, creating an agenda for a meeting, taking notes at said meeting, planning events, writing anything from diaries to screenplays, or any other task that calls for structured text.


With the free two week trial, you can try all of the features of Essentials and Pro without buying anything. After the trial, you can continue to use OmniOutliner to view documents for free.


• Filters: Use the search field in the toolbar to do a quick keyword filter.
• Document Stats: Row, word, and character count of the view are displayed in the bottom status bar.
• Distraction-Free Mode: Automatically hide the toolbar when switching to full screen mode.
• Side Margins: In full-screen mode, drag the margin borders to set the width of your outline independent of your display width.
• Cell Highlight: The cell currently being edited is indicated by a highlight on the left edge to give you more context of where and how big the cell is.
• Touch Bar: Use and customize the Touch Bar for quick access to features.
• Dark Mode: OmniOutliner’s UI adapts to match your document theme’s background color.
• Bottom Padding: You’ll no longer be stuck typing at the bottom of the window with the extra padding added below outlines.
• Typewriter Mode: Keep your eye line constant by automatically keeping the active row in the middle of the screen.
• New File Format: OmniOutliner 5 uses a new .ooutline format: a flat (zipped) file that is more compatible with third-party cloud sync platforms.
• Pro Document Compatibility: Documents containing Pro features are fully viewable in Essentials, along with an option to import a copy that removes all Pro content.


• Filters: Create and save complex filters based on status, column data, and boolean operations.
• Password Encryption: Add a password to your documents to secure them with AES-256 encryption.
• Slide-in Sidebars: In full screen mode, moving the mouse cursor to either edge of the screen makes the corresponding sidebar appear temporarily.
• Style Preview: A preview of the style you are inspecting is shown at the top of the inspectors.
• Multiple-Row Focus: Focus on multiple selections by command-clicking them in the sidebar section list.
• Resize Column to Fit: Select a column and have OmniOutliner adjust the width to fit your content for you with the Resize to fit button in the Column Type Inspector.
• Specify Column Widths: The Column Inspector now has an editable field for the column width. The outline column can also be set to automatically resize with the window or be set to a specific width.
• Keyboard Shortcuts: Easily customize keyboard shortcuts to your own liking within the app.
• Excel Export: Export to the Excel (xlsx) format.

What's New in Version 5.0.4

OmniOutliner 5.0.4 is a minor update containing a number of bug fixes.

Recent Changes

• General: The Paste command functions in the save panel and document name popover. This also allows TextExpander to work in these cases.
• Exports: Exporting password protected documents to non-OmniOutliner file formats will correctly leave the output unencrypted.
• Copy/Paste: Moving rows between an .oo3 file and an .ooutline file that has the note icon column in different positions will correctly map column values.
• Outline View: Using the Show All Notes command when notes are collapsed in hidden rows will properly toggle the notes and update the command to change to Hide All Notes.
• Outline View: When the Scale to fit page width print option is off, page break indicators will appear when resizing a column by dragging on the column edge.
• Paste: Using the Paste command when content is copied from Nisus Writer will correctly paste without styles.
• Paste: Using the Paste command when content is copied from Google Chrome's address bar will correctly paste without styles.
• Inspectors: The Long format label in the Column Type inspector for Duration columns has the correct background color.
• Sidebar: The checkboxes for Named Styles in the Styles sidebar no longer flicker when moving between rows with the arrow keys.
• General: Removed the locking ability of tabs in the sidebar and inspectors as they don't serve any purpose in v5.
• Style View: The Style View row highlighting will clear when clicking in empty space above or below the outline.
• Document Stats: Note content will be counted in the Document Stats even when the column displaying the note icons is hidden.
• Columns: All documents in Essentials mode will use an autosizing outline column regardless of how the setting is configured.
• Exports: Fixed exporting to docx format when non-image attachments are embedded in the file. These files are not supported by the format and will be represented by the name of the attachment.
• Exports: Fixed exporting to the xlsx format when cells contain nothing but a link.
