Archive explorer was a collection of several open-source and free projects geared around extracting data from the Twitter archive. Gathered around a web application that had 10,000 users during its lifetime, it made it possible to search, filter, order and group tweets, favorites, direct messages, followers and followings in a few seconds, at a time when Twitter did not yet provide an interface to explore the data of their archives. A mass tweet deletion tool, combined with the power of search, allowed you to target and empty any part of your Twitter account of its inappropriate content, while keeping a part of its history. As of the date of this post, Archive Explorer has removed almost 1.6 million tweets.
