Detextive is a tool for textual analysis. It can read any type of document OpenOffice supports (.doc, .odt, .html, .txt) as well as websites, rss feeds and it can even search google to find text on its own.

After you add all files/websites/etc. you want analyzed in this interface you will be taken to an advanced dynamic interface that will show you tagclouds of the documents, let you browse them and fetch more detailed analysis of specific words.

Note: This is alpha version software so certain things might not work. Also, adding text can take a long time if the source is very large, esp. in the case of google searches, so please be patient and allow up to 10 mins for it to complete.

Update: try our experimental widget and embed a detextive tag cloud on your webpage.
