Obsidian is a personal knowledge base and note-taking software application that operates on Markdown files. [3] [4] [5] It allows users to make internal links for notes and then to visualize the connections as a graph. [6] [7] It is designed to help users organize and structure their thoughts and knowledge in a flexible, non-linear way. [8] The software is free for personal use, with paid commercial licenses available. [3] [9]
Obsidian was founded by Shida Li and Erica Xu while quarantining during the COVID-19 pandemic. [10] Li and Xu, who had met while studying at the University of Waterloo, had already collaborated on several development projects. [11] Obsidian was initially released on 30 March 2020. [12] Version 1.0.0 was released in October 2022. [13] [14] Version 1.1, which added the Canvas core plugin, released in December 2022. [15] In February 2023, Steph Ango joined Obsidian as CEO. [16]
Obsidian is built on Electron. [9] It is a cross-platform application that runs on Windows, Linux, and macOS, as well as mobile operating systems such as Android and iOS. [9] There is no web-based version of the software. [11] The software may be customized by adding plugins and themes, which enable users to extend the software's functionality with additional features or integration with other tools. [9] Obsidian differentiates between core plugins, which are released and maintained by the Obsidian team, and community plugins, which are open-sourced through GitHub and are contributed by users. [17] Examples of community plugins include a Kanban-style task board and a calendar widget. [4] There are over 200 community made themes to use with the app.
Obsidian operates on a folder of text documents; [18] each new note in Obsidian generates a new text document, and all the documents can be searched from within the app. [9] [4] Obsidian allows internal linking between notes and creates an interactive graph that visualizes the relationships between notes. [9] [11] [4] Text formatting in Obsidian is achieved through Markdown, but Obsidian provides the instantaneous previewing of formatted text. [9]
A forum and Discord server are hosted by the developers. [19] [11]

A personal knowledge base (PKB) is an electronic tool used by an individual to express, capture, and later retrieve personal knowledge. It differs from a traditional database in that it contains subjective material particular to the owner, that others may not agree with nor care about. Importantly, a PKB consists primarily of knowledge, rather than information; in other words, it is not a collection of documents or other sources an individual has encountered, but rather an expression of the distilled knowledge the owner has extracted from those sources or from elsewhere.

It is headquartered in San Francisco, California, United States, with offices in New York, Dublin, Hyderabad, Seoul, Sydney, and Tokyo.
Zettlr is a free and open-source note-taking application that works with Markdown files. Files may be exported and imported from a variety of different formats using an integration with Pandoc, whilst integration with reference managers allows for insertion of citations into documents. Internal links may be created between notes, which can be visualised as a graph, enabling its use as a personal information management system or digital Zettelkasten. The name Zettlr is derived from the German word Zettel meaning 'note'.
Mermaid is an open-source JavaScript-based diagramming and charting tool that generates diagrams from text-based descriptions. Created by Knut Sveidqvist in 2014, the project originated from a need to simplify diagram creation in documentation workflows after experiencing issues with proprietary software file formats.
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.
The two main recent entries in the linked data PKM field are Roam and Obsidian
