It's a web app. You put in a page name and it starts. Works with many other wikis too.
CorHomo is a semiautomatic disambiguation tool for Windows and Linux created by Escaladix from the French Wikipedia. This program can select ambiguous links from the articles automatically and the only thing we need to do is click the title of the article we want to pipe, click validate, and then send. However, the most recent versions of this program are not working on the English Wikipedia.
Wikipedia Cleaner is another tool available for fixing links to disambiguation pages. It's a Java program that should be able to run on most platforms, provided a JVM has been setup first (Java 5 is required, Java 6 is recommended).
