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.
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.
TiddlyWiki may be saved as a single html file containing both the data (tiddlers) and the application (wiki), or the data can be saved on a per tiddler basis in text files (via extensions).
A TiddlyWiki opened from a file URI may save changes made back to the original file using one of the following techniques:
Starting from Firefox 57, only extensions developed using WebExtensions APIs will be supported on Desktop Firefox and Firefox for Android.
