• Users should be aware that software versions change over time, meaning some features or interface elements shown in tutorials may become outdated 25s.
• The application is available for download on desktop platforms, as well as through the App Store and Google Play for mobile devices and tablets 35s.

Pricing and Sync Services

• Obsidian is free for personal use, which distinguishes it from other tools like Roam Research and RemNote 50s.
• Paid options include Catalyst, which provides early access to insider builds, as well as optional add-on services like Sync and Publish 55s.
• Because Obsidian uses local file storage rather than being cloud-based, the Sync service is required to keep notes updated across multiple devices 1m15s.
• The Sync service allows for multiple vaults, and users can implement encryption passwords to ensure privacy when sharing an account across different users or devices 1m35s.

Community Support and Local Storage

• The Obsidian community provides support through an online forum and a Discord server, where developers are known to engage directly with users 2m5s.
• Obsidian stores data in local folders, meaning users can manage their note collections directly through their computer's file system 2m35s.
• Obsidian stores notes as individual files within a local folder on a computer, which the application refers to as a "vault." 0s

Vault Management and File Structure

• Users can initialize a vault by creating a new folder, opening an existing folder as a vault, or accessing the built-in help vault for guidance. 7s
• When a vault is created, Obsidian generates a hidden ".obsidian" folder alongside the user's content files, which are typically small in size. 38s
• Obsidian operates by directly manipulating files and folders on the user's system; for example, creating a note within the application generates an ".md" file in the corresponding directory, and moving notes between folders in the interface updates the file structure on the computer. 1m5s

Interface and Navigation

• The Obsidian interface consists of a main workspace in the center, a left side menu, a right side menu, and an action menu located on the far left. 1m35s
