In detail
Outliner
Hit Tab to indent and build a hierarchy. Collapse what you don't need, drag to move things around.
Focus mode
Zoom into any row and only its contents are shown. Breadcrumbs tell you where you are, and you can jump home anytime.
Markdown
Bold, links, checkboxes, and more render right where you type. Formatting markers only appear while editing — move away and they're gone.
Images & files
Add images by pasting or dragging, and resize however you want. PDFs and videos show as inline previews too.
Search
Cmd+F to search your whole outline. Matches get highlighted. Replace works too.
And more
Dark mode
Switch between light and dark themes. Automatically follows your system setting.
Tags
Use #tags to categorize and @tags for dates or status. Filter from the sidebar.
Bookmarks
Press Cmd+D to bookmark a row. Bookmarks appear at the top of the sidebar.
Reminders & Calendar
Any @tag with a date syncs to Apple Reminders or Calendar. Use @todo(3/15), @meeting(every monday 10:00), and so on.
Export
Export as Markdown, OPML, or plain text.
Auto backup
Restore past outlines from daily backups. Feel free to delete outlines you no longer need.
