This tool counts all the individual characters, bigrams and trigrams in the provided text, along with their proportions or percentages, and returns these in various structures and syntaxes. Use the results on their own, or fed them into the layout optimization framework (coming soon).
Feel free to play with this and compare e.g. various languages, the same novel written in different languages, different novels written in the same language, or your emails vs tweets vs professional texts. You may come to surprising conclusions.
