About Most Frequent Characters
This tool counts every character in your text (excluding whitespace) and ranks them by frequency. It's useful for spotting unexpected characters, comparing the distribution of two texts, or producing input for cryptanalysis exercises.
When to use it
- Spotting unexpected characters in pasted content
- Producing a character histogram for an article or transcript
- Cryptanalysis exercises (the classic 'E is the most common letter in English')
- Comparing the alphabet-share of two language samples
How it works
The text is iterated as Unicode code points. Whitespace characters are filtered out. Letters are lowercased for case-insensitive tallying; punctuation, digits, and emoji are kept as-is. Counts are sorted descending, ties broken alphabetically.
Examples
Hello, World!
l (3, 30%), o (2, 20%), …
Frequently asked questions
- Is whitespace counted?
- No — by default, whitespace is excluded. The shared statistics library can include it; this tool's UI hides it for cleaner output.
- Is it case-sensitive?
- No. 'A' and 'a' count as the same character. Letters are lowercased before tallying.
- How does it differ from letter-frequency?
- Letter-frequency only tallies letters; this tool also counts digits, punctuation, and emoji. Use letter-frequency for English-class style analysis; use this tool for inspecting arbitrary text.
