Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 130 Stack Exchange communities.

I have a website that has a tag cloud and I'd like to create a tooltip system that works exactly like the one on Stack Exchange.

On Stack Exchange if you hover on a tooltip you'll get the following tooltip:

Does anyone know if Stack Exchange uses a particular jQuery library or something to do this?

I believe that is a poput and not really a tool tip. You can achieve this by using divs and populating them and showing them on user keyboard or mouse events. –  ryadavilli Nov 30 '12 at 13:19

This is custom JavaScript code using jQuery, which is creating the contents <div> on the fly and put it in the proper position.

It's called MagicPopup and you can view the source in the main JavaScript file.

As for using it yourself, I'm not sure how legal this is.
