TiddlyWiki

TiddlyWiki (http://www.TiddlyWiki.com/), in its original form, is a kind of wiki that typically is edited by only one person and is completely self-contained in a single HTML file. It does not rely on a web server for storage, but rather on various solutions for letting the web browser save directly to a file on the users own PC. It uses HTML, CSS and JavaScript code. TiddlyWiki is supported by many extensions and plugins that modify how it works or what it can do.

TiddlyWiki is an open source single page application wiki. The content is divided into a series of sections, or Tiddlers. A user is encouraged to read a TiddlyWiki by following links rather than sequentially scrolling down the page.
