Gollum is designed to browse Wikipedia in an easier way than directly using the web browser.

Links external to Wikipedia are opened in the user's regular browser.

Gollum is opened from a regular browser and makes a window that puts the Wikipedia search bar on the toolbar.

[1] According to one blogger, Gollum provides a way to bypass censorship of Wikipedia in China.

[3] Though the website is available only in English and German, Gollum's GUI is available in more than 32 languages[4] and can browse nearly 50 Wikipedia editions.
