About Letter Frequency Counter
A letter frequency counter scans any block of text and tells you exactly how many times each letter appears, along with what percentage of the total that letter makes up. Paste in a sentence, a paragraph, or an entire document, and the breakdown appears instantly.
Counting letter occurrences by hand is realistic for a short sentence, but becomes impossible once you're working with a full paragraph or more, and that's exactly where this tool earns its keep. It's built for anyone who needs an exact count rather than a rough guess, whether that's for a cryptography exercise, a linguistics project, or a word-game strategy.
Cryptography students use it to spot patterns in a cipher, since letter frequency is one of the first tools used to crack a substitution cipher. Linguists and writers use it to study how closely a piece of writing matches typical English letter distribution, where E, T, and A usually dominate.
It's also handy for Scrabble and Words With Friends players checking which letters are overrepresented in their rack, or anyone curious about the letter patterns in a favorite quote or passage.
Paste your text in and get the full breakdown immediately.
