OmniOutliner
OmniOutliner is commercial outlining and idea-organization software for macOS, iPad, iPhone, and Apple Vision Pro, made by The Omni Group. It lets users create hierarchical nested lists, add rich text formatting, multimedia elements, notes, columns, and custom styles to structure content ranging from grocery lists and meeting notes to novel drafts and project plans. The app supports full keyboard control for fast composition, can sync documents across devices via OmniPresence or iCloud, and exports to OPML, HTML, DOCX, and plain text formats. It comes in free Essential and paid Pro editions, with the same license unlocking access across all Apple platforms.

The latest major version, OmniOutliner 6, released in January 2026, is also fully universal across Mac, iPad, iPhone, and Apple Vision Pro. If you are still running an older Intel-only build under Rosetta, update to the current version immediately through the Mac App Store or by downloading directly from omnigroup.com — either channel will serve the native build on M-series Macs. After updating, you will see noticeably better performance and battery life, and your outlines, preferences, and sync settings carry over without any migration step.
