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 character n-gram counter breaks your text into overlapping sequences of characters and counts how often each one appears, letting you analyze bigrams, trigrams, and longer character patterns. Paste your text, choose the n-gram size, and the tool tallies the sequences instantly, ranking them by frequency. Character n-grams are a core technique in linguistics, language detection, cryptography, search and autocomplete, and machine-learning features, where the patterns of letter combinations reveal a lot about a text. Seeing the most common sequences helps you study writing style, compare languages, and build text-processing tools. Doing this counting by hand is impossible at any real scale. Everything runs locally in your browser, so the analysis is immediate, free, requires no signup, and keeps your text private.

How to Use the Character N-Gram Counter
The Character N-Gram Counter works right in your browser — no signup, no installation. Follow these steps:
- Paste your text into the input area.
- Choose the n-gram size (e.g., 2 for bigrams, 3 for trigrams).
- Toggle case sensitivity and adjust minimum frequency as needed.
- Browse the frequency table to see the most common character sequences.
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.
Why Choose the Character N-Gram Counter?
Good analysis needs to be both fast and private. The Character N-Gram Counter processes your text locally and shows results as you work, so you can iterate on drafts and data freely, knowing the content is never transmitted or stored.
