Cloud Outliner vs Logseq

Cloud Outliner organizes plans, projects, ideas, and tasks as structured outlines on macOS and iOS. Its editor supports drag-and-drop reordering, multi-selection, checkboxes, automatic numbering, notes, rich text, and collapse or expand controls. Search works by outline name or text, while filters show checked or unchecked items. A multi-tier document manager adds color markers, password protection, templates, and duplication. Outlines can sync between Mac and iOS through iCloud and can also sync with Evernote. Export and sharing options include PDF, OPML, plain text, printing, email, messenger, and several apps or social networks; macOS also supports HTML export. Light and Dark themes are available. iOS lists read-only mode, indentation gestures, portrait and landscape support, and wireless keyboard shortcuts. The Mac free version requires a separate iOS Pro purchase for iCloud sync. Listed minimums are macOS 12, iOS 15, and iPadOS 15.

Logseq is a free, open-source platform for knowledge management and collaboration, with tools for notes, tasks, and PDF annotation. It supports Markdown and Org-mode files, and connects information through block references, backlinks, linked references, and queries. Logseq supports note sharing and real-time collaboration, and lists Zotero as an integration. The product says users keep their data locally and can work fully on-device; offline access is listed. It is available on web, Windows, macOS, Linux, iOS, and Android. A plugin and theme ecosystem extends the app, with the homepage listing more than 150 plugins and at least 30 themes. Logseq Sync provides encrypted file syncing across devices. Its public-beta Sync service does not support multiple people using the same graph at once, and the maker warns that data loss can occur. The database version is in beta, while the new mobile app and real-time collaboration features are in alpha; the maker also warns of possible data loss for these. Personal use is free forever. Sync Backer costs $5 a month and Sync Sponsor costs $15 a month, each described as a monthly recurring donation.
