Letter Frequency Analyzer
Count every letter in your text with percentages and bars — great for cryptograms.
Frequently Asked Questions
What is letter frequency analysis?
It counts how often each letter appears. In typical English, E is most common (about 12%), followed by T and A — a pattern used to crack substitution ciphers like Caesar and cryptograms.
Are spaces and punctuation counted?
They are excluded by default so percentages reflect letters only. A separate counter shows total characters, letters and non-letters.
Can I include accented letters?
Yes. Accented characters such as é are counted as their own letters in the "all characters" view when they appear in your text.
How can I use this to solve a cipher?
Match the most frequent letters in the cipher text to E, T and A in English, then test likely substitutions. The Caesar Cipher tool can then confirm the shift.
