Obsidian’s website describes the app as “a second brain for you, forever”. In plain English, that means a tool that can help you take and organise a colossal number of notes in a simple way, from basic study notes to a full-blown wiki.
The program makes use of the Markdown markup language to format text, making it easy to import and export files. This simplifies tasks such as using links to jump between notes and organising large amounts of information.
Obsidian is not FOSS but the free tier fully supports Linux, doesn’t require registration and has some very powerful features. The program itself was developed by Shida Li and Erica Xu, who were unhappy with the existing note-taking software on offer.
There’s also a thriving Obsidian community (https://obsidian. md/community) and a host of devs creating plugins to improve its rather minimalist interface.
