History
Founding and early development
Shida Li and Erica Xu, the two eventual co-founders of Obsidian, met while studying at the University of Waterloo. They both collaborated on several development projects prior to creating Obsidian, including the outliner tool Dynalist.
When the COVID-19 pandemic struck and they were left quarantining, they started working on Obsidian. Its development was motivated by shortcomings in other tools like MediaWiki, TiddlyWiki, and other note-taking apps. The idea was to build an app that was extensible in a similar manner to code editors and IDEs.
Obsidian's first beta release came not long after on March 30, 2020, and released its 1.0.0 version on October 13, 2022.
Business
On February 6, 2023, Steph Ango joined Obsidian as CEO after his contributions to Obsidian version 1.0.0 and his involvement in the community. Previously, he'd been working at the startup Lumi before it was acquired in 2021.
Major milestones
Major changes were made to how Obsidian plugins work on May 12, 2026 with the introduction of the Community Directory—a new official website for browsing plugins. With this release, the company announced that all plugin updates would be scanned automatically to flag issues relating to code quality and security. This allowed the team to quickly clear their plugin submission backlog, bringing the app's total community plugin count from around 2,700 to nearly 4,000. These changes aimed to address longstanding concerns over plugin security, particularly the one-time manual review before being published, at which point a bad actor could simply publish a new release with malicious code.
Availability
Obsidian is available on all major operating systems, including Windows, Linux, macOS, iOS, and Android—though it is not available as a web app. It is free for both personal and commercial use; though they offer subscription-based premium services, an optional commercial license, and a one-time payment to access beta versions of Obsidian.
Usage
Obsidian has been used for a wide variety of use-cases, in large part due to the extensibility of the app through plugins, which allow users to tailor Obsidian to their needs by keeping it as simple or advanced as needed. Some use-cases include writing, researching, learning, and task management.
According to a 2023 Fast Company article, Obsidian estimates that it has approximately one million users based on GitHub download counts. The article also reports that the app's Discord server has more than 110,000 members and its Reddit community has about 94,600 members, which ranks it in the top 5% of Reddit communities.
Features
Editing and organization
Files in Obsidian are stored in a local folder on a user's device called a "vault." Most notes make use of Markdown for formatting, though Obsidian can be used for spatial note-taking using its Canvas feature.
Notes can be organized through a variety of tools and metadata, including folders, tags, file properties, and bookmarks. Additionally, notes can be queried based on metadata to create a dynamic list, table, or other view using Obsidian Bases.
Bidirectional linking
Obsidian allows linking between notes, which can be formatted either as Wikilinks or traditional Markdown links. The "linked mentions" panel will show all links to the currently open note (backlinks); additionally links can be visualized using the graph view. The graph view is composed of nodes representing files and edges between nodes representing the internal links that connect notes together.
Plugins and customization
Users may customize Obsidian by using community-developed, open-source plugins and themes, which extend the software's functionality or customize the appearance of the app. Obsidian's plugin ecosystem is large, with plugins that support a variety of workflows.
External tools and integration
Obsidian Importer is a community plugin maintained by the developers to aid users in migrating from other note-taking apps to Obsidian. Obsidian Web Clipper is a browser extension that captures web content for use in Obsidian; it is available for Firefox, Safari, Chrome, and more. Obsidian CLI is a terminal program which is primarily useful for automations.
Premium services
Obsidian offers two subscription-based services: Obsidian Sync and Obsidian Publish. Sync is an encrypted file-synchronization services that syncs notes across devices. Alternatively, a file-hosting service (like Google Drive or Dropbox) or a peer-to-peer file sharing tool can be used for cross-device sync, though it is less convenient and something other note-taking apps offer for free. Publish is a web-hosting service that allows users to upload their notes to a dedicated website. Users can also publish vault content to the web using community plugins.
Reception
Reviewers praise Obsidian for its flexibility and many customization options. A reviewer at PCMag wrote about community plugins and themes enabling a wide variety of use-cases and workflows in Obsidian. Another reviewer at Fast Company said that Obsidian is not prescriptive about how users organize their notes, giving them a variety of options and formats for doing so.
Obsidian has been criticized for its learning curve and unfriendliness to beginners. Reviewers argue that Markdown can be challenging for users who are unfamiliar with it or desire advanced formatting. Others highlight that features users want are only available as community plugins, requiring time to understand and tailor the app to one's needs.
