Gears is an open source project that enables more powerful
web applications, by adding new features to your web browser:

Let web applications interact naturally with your desktop

Store data locally in a fully-searchable database

Run JavaScript in the background to improve performance

Gears is a plug-in that extends your browser to create a richer
platform for web applications. For example, webmasters can use Gears on
their websites to let users access information offline or provide you
with content based on your geographical location. To install Gears,
visit http://gears.google.com

Gears was designed to be used on both Google and non-Google sites. A
number of web applications currently make use of Gears, including two
Google products: Google Reader and Google Docs. Additionally, Zoho and Remember the Milk have been using Gears since its original launch. If you’re running Windows Mobile on your cellphone, Picasa Web Albums also makes use of Gears.

If you’re a developer interested in utilizing Gears on your site, visit the Gears developer site for more information.
