CarbonFin Outliner vs Legend

CarbonFin Outliner organizes thoughts, tasks, and projects in nested outlines. Tasks can contain subtasks, with progress indicators for parent tasks that have them. Its editor supports inline changes, cut, copy, paste, undo, redo, drag-and-drop reordering, search, and controls to collapse or expand items. Outlines can be tagged and filtered by tag, searched across the collection, archived, and optionally numbered. Each outline can include notes, with configurable checkboxes, note previews, and numbering. The iPhone and iPad app costs $4.99, paid once. Outliner Online is a free browser-based companion for syncing, editing, printing, importing, exporting, and sharing outlines. Outliner users can invite other Outliner users to view and edit shared outlines; published outlines can be viewed read-only by anyone with the URL. The app can sync outlines as OPML files with Dropbox or OneDrive, import OPML, and export plain text or OPML. Shared editing through Outliner Online is limited to iPhone or iPad app users. The app lacks native printing, though synced outlines can be printed through Outliner Online in a browser.

Legend brings notes, documents, tasks, email, files, outlines, and projects into one productivity interface. Users organize work in Boards made up of Panes, which provide separate work areas and context switching. Panes can show Outline, grouped, List, or Calendar views, and filters can use prefixes, item contents, words, or tags. Writing features include Markdown, formatting hotkeys, backlinks, and mirrors that connect notes with tasks. The Agenda view sorts tasks by priority and date. Legend says it syncs in real time across devices and collaborators, works offline, and resolves changes after devices reconnect. Its privacy policy describes client-side encryption before item data syncs to Firebase, with optional password encryption. The Free plan costs nothing and includes 10 Panes, one plugin sync account, and unlimited documents and items. Basic costs $5 a month billed annually; Pro costs $9 a month billed annually. The Browser Pane is not available in the mobile app, though saved links can open in a browser.
