- Text fitness
This online calculator computes text "fitness". That is, how similar the given text to other texts written in English language.

- Text fitness (version 2)
This online calculator calculates measure known as fitness score, of how given text is similar to a typical English text. It uses frequencies of unigrams, bigrams and trigrams to calculate fitness score. The reference frequencies are calculated from Leipzig Corpora Collection and can be downloaded from http://practicalcryptography.com/cryptanalysis/text-characterisation/quadgrams/. The less value you get, the better.

- Text fitness (version 3)
This online calculator calculates measure known as fitness score, of how given text is similar to a typical English text. It uses logarithms of probabilites with normalization to calculate fitness score. The reference frequencies are calculated from Leipzig Corpora Collection and can be downloaded from http://practicalcryptography.com/cryptanalysis/text-characterisation/quadgrams/. The less value you get, the better.
