TiddlyWiki introduces the division of content into its "smallest, semantically meaningful, components", referred to as tiddlers. Each tiddler is stored inside an HTML division that contains the source text and meta data in wiki markup. The purpose with this division is to enable easy re-use of content for different narratives and in different contexts.
For example, this section ("Tiddlers") could be a tiddler. In the TiddlyWiki user interface it would appear as it appears here but as a separate "note" visually distinct from other tiddlers.
The underlying HTML source code (which is not what the user faces) would be something like:
<div title="Tiddlers" modifier="John Smith" created="200811132220" modified="200811132225" changecount="3" tags="wikipedia section example code"> <pre>TiddlyWiki introduces the division of...
This same "tiddler" could then be reused in other contexts in the wiki.
A TiddlyWiki opened from a file URI may save changes made back to the original file using one of the following techniques:
- the Microsoft ActiveX FileSystemObject  for Internet Explorer
- TiddlySaver Java applet to extend Safari, Opera, Chrome/Chromium, and other browsers. Requires the Java runtime.
- Two techniques were developed for the Firefox browser:
- Mozilla File I/O  under the control of the UniversalXPConnect per-file preferences. That functionality was removed from Firefox.
- The TiddlyFox add-on for Firefox uses the Firefox SDK's simple-storage API. The add-on stopped working with Firefox around version 57 in 2017 which does not support the API.
TiddlyWiki is designed for customization and to be shaped according to users' specific needs, perhaps comparable to a high-end programming language. As such, it can be shaped into a wide and arbitrary range of special applications. Examples include niche note taking applications, to-do lists, presentations, collections, authoring tools, personal databases, recipe collections, etc.
Although there are many TiddlyWiki documents on the Web, the majority of TiddlyWikis reside on personal computers or in the cloud, or are exchanged over email, in a manner similar to word processing documents and spreadsheets. As a single HTML file, or saved as an HTA file in Microsoft Windows (allowing corporate IE lockdown to be bypassed), TiddlyWiki can be useful in corporate environments where red tape or IT resources might prevent the use of a wiki that requires a more complicated installation.
- The first version of TiddlyWiki was released by Jeremy Ruston in September 2004.
- BT Group bought Osmosoft in 2007 appointing Ruston as BT's "Head of Open Source Innovation".
- TiddlyWiki was selected as one of the Top 100 Tools for 2007 and 2008 by the Centre for Learning & Performance Technologies.
- In November 2011, Jeremy Ruston announced his departure from Osmosoft and commitment to continue development on TiddlyWiki.
- In December 2013 TiddlyWiki5 was released. It is a total rebuild of the original TiddlyWiki, based on HTML5 and with many significant improvements from lessons learnt over the years with the original TiddlyWiki. The original TiddlyWiki has come to be called TiddlyWiki Classic.
