Flesh
What is Flesh?
Flesh is a cross-platform, open source Java application designed to quickly analyze a document and display the difficulty associated with comprehending it. It is available for all platforms that support Java. Flesh has been released under the GPL (license for use).
After processing a document, Flesh produces two scores: the Flesch-Kincaid Grade Level and the Flesch Reading Ease Score. Each of these scores is calculated after determining the number of sentences, words and syllables a document contains. Using those numbers, the Flesch-Kincaid Grade Level and Flesch Reading Ease Score can then be calculated.

What Does Flesh Tell Me?
In brief, it tells you how difficult documents will be to comprehend by calculating a document’s Flesch-Kincaid Grade Level and Flesch Reading Ease Score. Like all readability indices, the Flesch-Kincaid Grade Level and the Flesch Reading Ease score only provide estimations and are only meant to be used as such.
The Flesch-Kincaid Grade Level is an index that gives the years of education required to comprehend a document. For example, a document with a Flesch-Kincaid Grade Level score of 10 would require that a reader have about 10 years (or a 10th grade level) of education to comprehend the document. It can be calculated using the following equation:
(0.39 × Average Sentence Length) + (11.8 × Average Syllables per Word) - 15.59
The Flesch Reading Ease Score indicates on a scale of 0 to 100 the difficulty of comprehending a document. A score of 100 indicates an extremely simple document, while a score of 0 would describe a very complex document. A Flesch Reading Ease Score in the range of 40–50 would correspond to a relatively complex document that might score a 12 as its Flesch-Kincaid Grade Level. The Flesch Reading Ease Score can be calculated by using the following equation:
206.835 - (1.015 × Average Sentence Length) - 84.6 × Average Syllables per Word
