Welcome to OmniOutliner 4, an amazingly flexible yet lightweight program for creating, collecting, and organizing information. Use OmniOutliner’s document structure to brainstorm new ideas, drill out specifics, and construct a beautiful document for sharing. 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.


• Sync: Keep your documents up to date between Macs or to OmniOutliner for iPad with OmniPresence, our free sync technology.
• Organization: Add structure to your thoughts and notes by creating easy-to-manipulate collapsible outlines (lists of lists of lists).
• Sections: See your whole document structure in the sidebar; just click a section to instantly focus in on it.
• Columns: Use columns to associate different types of information with each item—pop-up lists, checkboxes, numerical values, dates, durations, or rich text.
• Styles: OmniOutliner helps you format on the fly with a rich Styles system designed to give you everything you need to apply style changes—from one word at a time to document-wide. Change once; change everywhere.
• Saved templates and themes: Save your favorite documents as templates; then use them as starting points for new documents or apply their styles to an existing document as a theme.
• Attachments: Insert any kind of file; images and other media appear right inline.
• Audio recording: Capture audio directly into your documents so you can, for example, refer back to the lecture or interview that you’re taking notes on.
• Exporting: OmniOutliner documents can be exported as plain text, rich text, OPML, HTML, and more.

PRO FEATURES (Available via in-app purchase)

• Column Visibility: Feel free to add as many columns as you like to your document, and show only the ones you really need at the moment.
• Folded editing: OmniOutliner actively collapses the text of all rows except the one you’re editing, so that you can see more of your document at once.
• Advanced styling: Get more control over nerdy details like custom spacing schemes and manual page breaks.
• AppleScript support: Create AppleScript shortcuts for complex tasks, automate the things you do over and over, and turn OmniOutliner into a whole new app; you’ll get more done, and with fewer mistakes.
• And more: Show notes in a separate pane, export to Microsoft Word format, and even build your own export plug-ins.

Disappointing, underwhelming, expensive

Omnioutliner 4.x is a slow motion train wreck.
Useless as it is.
Read on for the fugly details…

After countless crashes and total data loss during the first hour at it, I had enough of an aftertaste.
The worst thing is that despite the reviews and warnings, I still wanted to try and like this program (hence the second, compassionate star). I got burnt with OmniGraffle Pro before, but I didn’t learn my lesson.
This standard version has been crippled in a ridiculous way. The most desirable features of the Pro version (except export to Word formats) ARE STILL IN THIS STANDARD VERSION, and they function OK. Tinker a bit, and you’ll be able to find a way of using most of them, just without any handy GUI controls... The manufacturer eliminated part of the user interface, in an attempt to nickel-and-dime the user, making the experience annoying in a negatively deliberate way; a fleece. Yet, it seems that even this dumbing down doesn’t work as intended. Go figure...
If this product ever works as intended, price point should be cut in half and Pro version “extras" should be the standard feature set to make OmniCrashliner 4.x acceptable.
