Character N-Gram Counter
Count character-level n-grams in any text. Analyze bigrams, trigrams, and higher-order character sequences for linguistic analysis.
About This Free Online Character N-Gram Counter
Our free online Character N-Gram Counter extracts and counts character-level n-grams from any text. Analyze bigrams (2-letter sequences), trigrams (3-letter sequences), or any n-gram length up to 10 characters. See which character combinations appear most frequently in your text. Useful for linguistics research, stylometric analysis, cryptography, and pattern recognition in text. All processing runs in your browser.

Frequently Asked Questions About Character N-Gram Counter
What are character n-grams used for?
Character n-grams are used in linguistics (stylometry, authorship attribution), cryptography (frequency analysis), NLP (language modeling), and text classification.
What is the difference between bigrams and trigrams?
Bigrams are sequences of 2 characters (e.g., "th", "he"), trigrams are sequences of 3 characters (e.g., "the", "and"). Higher n-grams capture longer patterns.
Why would I use case-insensitive mode?
Case-insensitive mode treats "The" and "the" as containing the same n-grams. This is useful for standard frequency analysis where case differences are not meaningful.
