Some of the many great features in DocumentCloud include its ability to create text versions of PDFs and build up stats from your uploaded files. But what if you need to analyze thousands, or even hundreds of thousands of documents? Then you’ll probably want to look at Overview, a document-mining tool built with investigative journalists in mind.

Overview can import documents from a range of sources, including DocumentCloud, and can handle anywhere from a few dozen pages to millions of pages. Overview can visualize the data in the document collection in a range of ways from word clouds to network graphs. It also has a range of search tools that make it relatively simple to filter your data for specific information. One of its best features is that is can automatically group your documents into folders based on their content. And, like DocumentCloud, it has built-in optical character recognition (OCR) so you can view your documents in their original format or as plain text. Add to that the ability to add tags and notes, and suddenly mining thousands of documents doesn’t seem so daunting.
