Saplo's API reads text so you don't have to

Imagine a technology that can read and “understand” any block of text. That’s what Swedish startup Saplo does. It’s a sort of “Pandora for text” whose ultimate aim is to filter articles, tweets, ads or any other types of text based on your preferences. It can also group together similar text items, find related ones and even judge whether the text expresses positive or negative sentiments.
