A standard edit dialog on a tiddler

TiddlyWiki is a wiki-modeled client-side single-page application written by Jeremy Ruston that is designed to be used as a personal notebook. It is a single self-contained HTML file that includes CSS and JavaScript code. When the user downloads it to their PC, TiddlyWiki can save the entered information by overwriting itself on the user's disk, at the user's request. Following TiddlyWiki conventions, users can make a new entry, called a tiddler, in their local copy of the TiddlyWiki file and save it for future reference. Existing tiddlers can also be modified or deleted in the same way. Because it runs under most browsers and requires no installation, it can be easily used as a portable personal wiki.

TiddlyWiki is published by UnaMesa – a non-profit association – under a BSD open source license and is thus freely available. Developer Jeremy Ruston describes it as experimental, and in that spirit many people have used the original HTML file to create TiddlyWiki Adaptations. These fall under two general categories: those that retain the client-side write only feature, and those that add server-side file writing to make TiddlyWiki more like a traditional wiki. Links to both these kinds of Adaptations are put in the original TiddlyWiki file as they become known. TiddlyWiki Adaptations typically add features that were not originally envisioned by Ruston, and some of these features have been included in newer versions of TiddlyWiki.

A feature that sets TiddlyWiki apart from a standard wiki implementation is its content presentation. Jeremy Ruston had this to say about it:

A TiddlyWiki is like a blog because it's divided up into neat little chunks (tiddlers), but it encourages you to read it by hyperlinking rather than sequentially: if you like, a non-linear blog analogue that binds the individual microcontent items into a cohesive whole. I think that TiddlyWiki represents a novel medium for writing, and will promote its own distinctive writing style.

TiddlyWiki can also be used as a personal productivity tool using the methods in David Allen's book Getting Things Done.[1]

From Wikibooks, the open-content textbooks collection, using TiddlyWiki version 2.1.3.

TiddlyWiki ( is a kind of wiki that typically is edited by only one person and is completely self-contained in a single web page. It uses HTML, CSS and JavaScript code. TiddlyWiki is open source and supported by many extensions and plugins that modify how it works or what it can do.

Using a TiddlyWiki to build a web page is a good idea because:

  • it's fun
  • it's simple to create
  • it's simple to update
  • it's simple to customise
  • it's an innovative way of presenting text

This book will serve a reference for people who want to learn to read, write, customise or develop/code a TiddlyWiki. No technical knowledge will be assumed. Screenshots will be used liberally for faster learning, and the reader is encouraged to tinker with their own TiddlyWiki while reading this book.
