Todoist

Todoist is a simple web based to-do list that I quite like. Though it is not specifically designed for GTD, it is more of a help to me than the resource hog ThinkingRock ever was. Todoist is usable right away, but you'll be able to get much more out of it by reading the help sections, describing various shortcuts for adding, editing and structuring tasks, inserting links and so on. It also has a JavaScript API which I use to synchronize birthdays between my custom database and Todoist.

Todoist Anywhere

Todoist Anywhere is a bookmarklet that embeds Todoist into any website (especially Google Mail), potentially making it easier to put data from that site into your todo list.

My version

Context	Behaviour	Comment
In a new or empty tab	Opens the Todoist start page	Configure the start page via Todoist preferences
On the Todoist startpage	Reloads the page	A normal bookmark wouldn't do that since Todoist uses URL fragments
Anywhere else on todoist.com	Switches to the start page	This does not cause a reload
Anywhere else on the web	Triggers the default behaviour of Todoist Anywhere

Installation

Drag & drop the following link to your bookmark bar to install the bookmarklet: ✓ Todoist Tasks.

		var script = doc.createElement('script');
		doc.todoist_script = script;
		script.type = 'text/javascript';
		script.src = 'http://todoist.com/anywhere/getJavaScript';

void(0);

If you have modified the bookmarklet, you can reformat the source code with the Online javascript beautifier. I used a bookmarklet maker to shorten the code somewhat.
