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, rearrange them and construct beautiful documents 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.

Draft a simple to-do list, create an agenda for a meeting, take notes, plan events, write 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. 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 are displayed in the bottom bar.
• Distraction-Free Mode: Automatically hide the toolbar when switching to full screen.
• Side Margins: drag the margin borders to set the width of your outline independent of your display width.
• Cell Highlight: The cell being edited is indicated by a highlight on the left edge to give you more context.
• Touch Bar: Use and customize the Touch Bar for quick access to features.
• Dark Mode: OmniOutliner’s UI adapts to match your document theme.
• 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 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 platforms.
• Pro Document Compatibility: Documents with 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 secure your documents (AES-256 encryption).
• Slide-in Sidebars: In full screen, moving the cursor to either edge of the screen makes the sidebars 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 section list.
• Resize Column to Fit: Select a column and have OmniOutliner adjust the width with the Resize to fit button in the Column Type Inspector.
• Specify Column Widths: The Column Inspector now has an editable field for the width. Columns can also be set to resize with the window or be set to a specific width.
• Keyboard Shortcuts: Easily customize shortcuts to your own liking.
• Excel Export: Export to xlsx format.

Extremely Mediocre App

OmniOutliner is severely lacking in basic features like changing fonts. After exploring the app, searching support and then reluctantly contacting support--who were not helpful, I still cannot easily alter the font.

The outliner does not support numbered outlines. When exporting and sharing, if one wants to refer to a section, one cannot.

Having used less expensive yet more useful outlines, I strongly do not recommend this product.

I am sticking with v4, disapointed with 5

Omnigroup products have been an integral part of my life. I have paid Omnifocus Pro 2 & 3, Omnioutliner 3 Pro, 4 Pro, 5 Essentials, even GraphSketcher (paid for it back then).

I upgraded from OO 4 Pro > OO 5 Essentials. I can't believe the limited functionality. If I don't spend $60 for the Pro version, numbering and bulleting are unavailable to me. OO 5 Essentials has so little functionality (despite being a PAID product) that I cannot even use numbered bullets. C'mon Case, I paid you money for a product that has significantly less functionality than many free/cheaper mac apps. I don't want to use them. I want to use an support omnigroup, but you are making it very difficult when you distribute an app like OO 5 Essentials.

Do not download the trial version. It will corrupt all the existing files started in past versions.

Developer Response ,

Please contact us at or by phone Mon - Fri, 10am - 5pm Pacific at 1 (206) 523-4152 if you have not yet and we’ll be happy to help you figure out what happened and if your files are recoverable. Using version 5 will not even touch any existing files if they're never opened. If the corruption is a backwards compatibility problem, we will be able to help you with that.
