Obsidian is a highly customizable note-taking and knowledge management application designed to serve as a "second brain." Unlike many cloud-based tools, Obsidian operates on local Markdown files, ensuring that your data remains private, accessible offline, and future-proof. It is built on the principle of data ownership, allowing users to maintain their knowledge base without being locked into a proprietary ecosystem.
Obsidian is free for personal use. For users requiring additional features, they offer paid services including Obsidian Sync (for encrypted cross-device synchronization) and Obsidian Publish (to turn notes into public websites). Commercial licenses are required for use in organizations with two or more employees.
Q: Where are my notes stored? A: Your notes are stored as plain Markdown files on your local hard drive or mobile device.
Q: Is Obsidian open source? A: No, Obsidian is proprietary software, but it uses open file formats (Markdown), so your data is never locked in.
Q: Can I use Obsidian on mobile? A: Yes, Obsidian is available for macOS, Windows, Linux, iOS, and Android.
Q: Do I need an internet connection to use it? A: No, Obsidian works entirely offline. Internet is only required for initial download, updates, or using Sync/Publish services.
Q: How do I sync my notes across devices? A: You can use the official Obsidian Sync service or third-party solutions like iCloud, Dropbox, or Git since the files are local.
