Has a steep learning curve; requires understanding of markdown, plugins, and graph concepts to use effectively

Extremely intuitive; opens instantly and requires zero setup or technical knowledge

Offers bidirectional linking, graph view, 1000+ community plugins, templates, canvas, and full markdown support

Supports checklists, tables, attachments, quick notes, and tags, but lacks advanced linking or extensibility

Works on Windows, macOS, Linux, iOS, and Android; sync via Obsidian Sync (paid) or third-party services like iCloud or Dropbox

Syncs seamlessly via iCloud across Apple devices; web access available but Windows/Android support is non-existent natively

Free for personal use; Obsidian Sync costs $4/month and Publish costs $8/month; one-time commercial license is $50

Completely free and pre-installed on all Apple devices with no subscription required

Notes are stored as plain-text markdown files locally; you fully own your data and can use any editor or backup tool

Data is stored in iCloud in a proprietary format; encrypted but tied to Apple's ecosystem and account

Fast for a local app; heavy plugin use can slow startup, but core performance is solid even with large vaults

Near-instant open times and rock-solid reliability; occasional iCloud sync delays can occur with large attachments

Highly extensible with themes, CSS snippets, and a massive plugin ecosystem covering everything from task management to Kanban boards

Very limited customization; font size and checklist styles are the extent of formatting control
