OmniOutliner Overview

OmniOutliner is a flexible outlining application for macOS (and iPad) from The Omni Group, built for organizing information in structured, expandable lists. It goes beyond a simple list with multiple columns (for text, numbers, dates, checkboxes, and pop-up menus), styles, and the ability to collapse and expand sections, which makes it useful for everything from to-do lists and meeting notes to writing outlines, planning, and lightweight project tracking. It supports filtering, rich text, attachments, and export to formats like Word, HTML, and plain text, and syncs across Apple devices. It is a favorite among Mac users who think in outlines. The desktop application is downloaded and installed from the developer's official site. You can reach the official OmniOutliner download from The Omni via the link on this page.
