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.

• 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.

What's New in Version 5.0.2

OmniOutliner 5.0.2 is a minor update focused on bug fixes and stability improvements.

Recent Changes

• Interface: There are more ways to set the outline column to auto-size with the window. This option is now available in the contextual menu for the outline column and under View > Columns.
• General: Fixed issues with unlocking the Pro Edition while the trial is in Essentials mode. This will fix the issue with only the Essentials templates appearing in the Resource Browser and documents temporarily showing the warning about Pro features at launch.
• Copy/Paste: Pasting data from Excel no longer results in a PDF.
• Copy/Paste: Pasting data from Numbers will retain the column structure.
• Outline View: Text no longer starts to blur at wide widths when editing a row.
• Toolbar: Fixed the vertical alignment of toolbar buttons in small size mode.
• Interface: Stopped the outline view and word count from shifting unnecessarily while toggling the sidebars.
• Interface: Resizing the sidebar in overlay mode while in full screen will keep the outline view positioned correctly.
• Outline View: Column titles will always display their background color.
• Attachments: Duplicate attachment names will be renamed in a more friendly manner.
• Copy/Paste: Attachments can be pasted directly into row or notes instead of resulting in a file path.
• File Upgrading: Converting .oo3 or .oo3template files will result in the flat format to avoid unexpected size increase due to being uncompressed.
• File Upgrading: Converting an .oo3 file that is set to a dark theme will have the filter tab in the sidebar immediately after conversion.
• Resource Browser: The Templates section of the Resource Browser will show the subfolders when the app is launched for the first time.
• Stability: Fixed a crash when trying to edit a filter that ended up set to a setting not supported by the column type.
• Stability: Fixed a crash when trying to edit a filter that has been set to filter for a pop-up list entry that no longer exists. The filter will still be set to the missing entry and will continue to work if that entry is re-added to the column. After changing the filter away from the entry, it will no longer appear.
• Stability: Fixed a crash when tabbing out of the column width field after clearing the value.
• Stability: Fixed a crash triggered by changing the column type while the pop-up list is open for that column in the outline.

For more details, please see the longer release notes which are available from the Help menu.

Lacks features and elegance of many modern outliners

I paid for it, but I never use it... I prefer the “essentials” version because it doesn’t get in my way with a lot of useless features that I never use when compared with the “pro” version, but I still feel that OO can’t hold a candle to some of the web-based outliners that are out now in terms of features or user experience. And there are other MacOS apps that more closely match the experience offered by these web apps. This product feels dated.

Don’t bother!

This version works for 15 days. After that you can only use it in read-only mode unless you purchase the product. Not worth paying for.

Terrific outlining app, but has some bugs with new version

Omnioutliner is a terrific outlining app, easy to use, and a ton of customization to fit your needs.

Two things keep it from being 5 stars:
1) This new version is a little buggy, but Omni Group will work them out. Had some crashes with syncs to iOS devices, otherwise seems mostly stable.
2) Wished there was a way to have a line showing the parent-to-child items like Workflowy and show with theirs. If the developers could add that, then I would give it 5 stars easily.
