Kosshi is a fast, native outliner. Simple and smooth on large outlines. Available on Mac, iPhone, and iPad — one purchase covers all three. Outliner Hit Tab to indent and build a hierarchy. Collapse what you don't need, drag to move things around. Zoom In / Zoom Out Zoom into any row and only its contents are shown. Breadcrumbs tell you where you are, and you can jump home anytime. Markdown Bold, italic, highlight, links, checkboxes, code blocks, and LaTeX math all 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. Apple Pencil Sketches Draw sketches with Apple Pencil on iPad. They sync to Mac and iPhone through iCloud. Search Cmd+F to search your whole outline. Matches get highlighted. Replace works too. 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. Internal Links Type [[ to search and link to another row. Build a web of connected outlines. Bookmarks Press Cmd+D to bookmark a row. Bookmarks appear at the top of the sidebar. Prose Mode Switch a row to Prose Mode for long-form writing. Bullets disappear and children stay expanded. 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. Keyboard Shortcuts Collapse, move, indent — all without reaching for the mouse. Export Export as Markdown, OPML, or plain text. Your data is never locked in. Auto Backup Restore past outlines from daily backups. Feel free to delete outlines you no longer need. iCloud Sync When iCloud is available, your outlines sync across Apple devices via CloudKit. Data is stored in your iCloud account, and the developer cannot access its contents. Pay Once Built natively for speed. Launches quickly and works offline.
