Wikilinks
Definition: links written as [[Page Name]] that resolve to a page in the same vault or wiki. Used in MediaWiki, Obsidian, Roam, Logseq, and MindWiki as the default linking syntax inside a knowledge base.
Plain-English definition
A wikilink is a link written as [[Page Name]] that resolves to another page in the same vault. The bracket syntax originated in MediaWiki (the engine behind Wikipedia) and is now standard across personal knowledge tools.
Why they're useful
- Lower friction than typing a full URL or path — you reference a page by its title.
- Bidirectional by default — every wikilink also creates a backlink on the linked page.
- Resolution works even if the target page doesn't exist yet (a "ghost link").
- Renaming a page typically updates all wikilinks pointing at it.
In MindWiki specifically
- Syntax: [[Page Title]] resolves by title or path.
- Live preview renders the wikilink as a clickable pill while you write.
- The graph view uses wikilinks as edges between pages.
- Renaming a page can update wikilinks across the vault via the updateWikilinks helper.
