Applications
Useful for cryptanalysis, linguistics research, text stylometry analysis, and understanding writing patterns. Writers can track repetition, and students can analyze text structure and vocabulary diversity.
How It Works
Character frequency counts every character in the text. Word count splits on whitespace. Sentence count splits on . ! and ?. Letter frequency filters to A-Z only, then sorts by count descending. Bigrams and trigrams are 2-char and 3-char sliding windows across the full text including spaces and punctuation. Each bar shows the percentage relative to the total count in its category.
Fun Fact: The letter 'E' occurs roughly once in every eight characters of English text — making it the most frequently used letter by a wide margin! In fact, 'E' accounts for about 11-12.3% of all letters in the English language.
