P.A.N.

P.A.N. (A.K.A.: Poetry Analyzer, Textual Analyzer) is a freeware application that allows users to analyze virtually any sort of text (fiction, newspaper, poetry, history text book). It does this by parsing text, determining sentence structure, identifies mood and tones of sentences. Also identifies primary imagery and themes. Poetry Analyzer's website states that a unique analysis of text is accomplished by studying that which is most overlooked, and considered not relevant.
