Obsidian is a proprietary personal knowledge base and note-taking application that operates on markdown files. [2] [3] [4] The software is free for personal and commercial use; only the offered cloud services, optional commercial licenses, and early access versions are paid. [5] It is available as desktop versions for macOS, Windows and Linux as well as for mobile operating systems such as iOS and Android, [6] but not as a web application.
Shida Li and Erica Xu, the two eventual co-founders of Obsidian, met while studying at the University of Waterloo. [7] They both collaborated on several development projects, including note-taking software Dynalist.io since 2015. [8]
When the COVID-19 pandemic struck and they were left quarantining, they founded Obsidian—which had been envisioned two years before the first beta version released. [9] Obsidian's first beta release came not long after on March 30, 2020, [10] and released its 1.0.0 version on October 13, 2022. [11] [12]
On February 6, 2023, Steph Ango joined Obsidian as CEO after his contributions to Obsidian version 1.0.0 and involvement in the community. [13] Previously, he'd been working at the startup Lumi before it was acquired in 2021. [14] [15]
On November 11, 2024, Obsidian launched its Obsidian Web Clipper browser extensions for all major browsers on desktop and mobile, including Firefox, Chrome, Safari, and other Chromium-based browsers. [16]
On February 20, 2025, Obsidian announced that its commercial licenses were now completely optional, citing, "The Commercial license terms were confusing and added unnecessary complexity to our pricing" as the reason for the change. Companies that purchase 25 or more commercial licenses are featured on the Obsidian Enterprise page. [17]
Obsidian is built on the cross-platform Electron framework, allowing for the application to run on desktop operating systems like Windows, Linux, and macOS. There are also available native apps for mobile operating systems such as Android and iOS [18] using the cross-platform Capacitor native runtime. [19] While built using web technologies, it is not available as a web app.
Obsidian is free for both personal and commercial use; they offer paid premium services (Obsidian Sync and Obsidian Publish), an optional commercial license, and the Catalyst license, which grants users access to beta versions of Obsidian. [5]
A community forum and Discord server are hosted by the developers. [20] [7] Both allow users to ask for help, share tips & workflows, and discuss knowledge management. The forum can additionally be used for submitting feature requests and bug reports. [21]
Obsidian is particularly suitable as a knowledge database for personal knowledge management and as software for creating notes that works with Markdown files. [22] [23] It is designed to help users organize and structure their thoughts and knowledge in a flexible, non-linear way. [18]
Obsidian has also been described as a tool that facilitates a digital method of Zettelkasten, a note-taking methodology which heavily involves connecting related notes together, due to its internal linking and graph visualization features, which can reveal connections between notes. [24] [22]
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. [25] [26] Some use-cases include writing, [27] task management, [3] and learning. [24]
Obsidian operates on a folder of text documents named a "vault"; [28] each new note in Obsidian generates a new text document, and all documents can be searched from within the app. [18] [3] Text formatting in Obsidian is achieved through markdown, with the ability to switch between a raw text (Source Mode) and a pre-rendered (Live Preview) mode while editing. [18]
Obsidian allows internal linking between notes, formatted either as Wikilinks or traditional markdown links, with links contributing to the interactive graph view that visualizes the relationships between notes. [18] [7] [3]
Users may customize their Obsidian vaults by using plugins and themes, which extend the software's functionality with additional features or integration with other tools and customize the appearance of the app respectively. [18]
Obsidian differentiates between core plugins, which are released and maintained by the Obsidian team, and Community plugins are primarily developed by members of the Obsidian community under open source licenses and hosted on GitHub (although the Obsidian team does develop the "Importer" and "Maps" plugins as community plugins). [29]
Obsidian isn't prescriptive about how users organize their notes. Bases is a core plugin enables users create database-like views of their notes, which can be customized to look like dynamic tables or even maps. [18] Canvas, another core plugin, provides a freeform, infinite 2D space where users can arrange and connect notes, attachments, and web pages. [20]
The graph view is a visualization of notes in the vault and the connections between them. It is composed of nodes representing files (typically markdown documents) and edges between nodes representing the internal links that connect notes together. [30]
Access to a broad overview of a vault and the connections between notes facilitates discovery of new connections that may not have been obvious when looking at just a single note in isolation. [24] : 298 [22]
Obsidian Web Clipper is a browser extension available on all major browsers that allows users to highlight and "capture" information from the web and save it in their vault in a markdown format, along with metadata. [18]
Obsidian Sync is a subscription-based encrypted file synchronization service. [18] Obsidian doesn't have cross-device sync by default because it stores notes locally on a user's hard drive. [18] [24] : 298 However, because files are stored locally, users also have the option of using their own file sync solutions. [20] Alternative tools to Obsidian Sync often include traditional cloud services (such as iCloud, Google Drive, and Dropbox) [24] or peer-to-peer file synchronization tools like Syncthing and Resilio Sync. [18]
Obsidian Publish is a subscription-based web hosting service that allows users to publish their notes onto the Web. Users can alternatively make use of external tools and community plugins to publish vault content as well. [20]
Today, we are familiar with interlinked pockets of information in the form of hyperlinks on webpages such as Wikipedia. However, in the context of personal knowledge systems, the last year has seen an explosion of 'Personal Knowledge Graph (PKG)' tools such as 'Roam Research', 'Obsidian', and 'Notion', which digitise and personalise this powerful concept. Using bidirectional links, these tools connect notes in ways that sit between traditional word processors and more advanced databases with graphical functions. PKGs represent an evolution in knowledge aggregation and assimilation through the ability to 'visualise' personal learning in graphical form. Rather than our hard-won notes being lost in personal silos of projects, folders, and just the passing of time, such graphs allow researchers to literally pan out and visualise their knowledge as a network, revealing nascent and serendipitous connections between percolating notes of ideas, insights, concepts, quotes, and questions.
However, there are some recent entries into the PKM space that might just fit the full bill. Both Obsidian and Roam, which will be discussed later, are relatively new applications that get us a little closer to that perfect PKM solution, and they add a new wrinkle. They are both conversant in linked data and can be used as networks of linked information that live on your computer or, with a few tweaks, on a shared server or other shareable drive.
