Obsidian vs Org mode

Obsidian is a note-taking app for keeping notes and building a personal knowledge workspace. Its core app is free, has no sign-up requirement, and stores notes on the user's device so they remain available offline. It runs on Windows, macOS, Linux, iOS, Android, and as a Chrome extension. Canvas provides an open workspace for research, brainstorming, diagrams, and ideas; thousands of plugins and an open API allow workflow customization. Shared vaults support team work with real-time updates. Sync adds synchronization and version history: Standard costs $5 per user per month billed annually, with one vault, 1 GB of storage, a 5 MB maximum file size, and one month of history. Plus costs $10 per user per month billed annually, with 10 vaults, 10 GB, a 200 MB maximum file size, and 12 months of history. Publish is $10 per site per month billed annually and includes up to 4 GB hosting per site. It offers themes, custom domains, password protection, and SEO optimization.

Org mode is a structured plain-text format and a mode for GNU Emacs, suited to work ranging from notes and markup to literate programs. It combines task planning, time tracking, document editing and publishing. Tasks can have TODO states, priorities, deadlines, schedules and tags, with clocking and customizable agendas. Org documents use nested sections that can be folded or unfolded, and tables support formulas, references, and CSV or TSV imports. Org Babel runs source blocks in more than 80 languages. Documents can be exported to formats such as HTML, LaTeX, ODT and Markdown, and projects with multiple Org files and resources can be published. Org Capture collects structured information from Emacs and other applications, including browsers and PDF viewers. The full feature set is exclusive to GNU Emacs, though third-party file tools are listed for Android, iOS and web. Org is free, included with GNU Emacs, and also installable through package management or its Git repository. Recent releases require a recent Emacs version.
