How to Find Unique and Distinct Letters in Any Text (2026)
You can find every unique and distinct letter in any text using our free Find Unique Letters tool. Extract all unique alphabetical characters, view how many times each one appears, and sort the results alphabetically or by frequency. Toggle case sensitivity to treat uppercase and lowercase separately or combine them. All processing runs in your browser for complete privacy.
What Are Unique Letters in Text
Unique letters are the distinct alphabetical characters that appear in a piece of text, counting each letter only once regardless of how many times it occurs. For example, the text “Hello World” contains the unique letters H, E, L, O, W, R, and D — 7 distinct letters out of 10 total characters. Unlike a general character frequency counter that tracks every symbol including spaces and punctuation, this tool focuses exclusively on A-Z and a-z letters, making it ideal for word games, cryptography, pangram checking, and vocabulary analysis.
How to Use Our Find Unique Letters Tool
- Open the Find Unique Letters tool and paste or type any text into the input area.

Common Use Cases
- Pangram checking — verify that a sentence contains every letter of the alphabet. “The quick brown fox jumps over the lazy dog” is the classic perfect pangram.
- Word games — analyze letter diversity in Scrabble, Wordle, and other word games to find unused or overused letters.
- Cryptography — study letter frequency distribution in ciphertext as the first step in breaking substitution ciphers.
- Writing analysis — check letter variety in your writing to identify overused or underused letters.
FAQ
How is this different from the Character Frequency Counter?
This tool focuses specifically on alphabetical letters (A-Z, a-z) and ignores numbers, spaces, punctuation, and symbols. The Character Frequency Counter counts every character type including spaces, digits, and punctuation marks.
Does this include accented characters like é or ñ?
Yes. Letters with diacritics such as é, ñ, and ü are treated as distinct letters when case-sensitive mode is on, or normalized to their base letter when case-sensitive is off.
What is a pangram?
A pangram is a sentence that contains every letter of the alphabet at least once. The most famous English pangram is “The quick brown fox jumps over the lazy dog,” which uses all 26 letters. Our tool can instantly confirm whether any text is a perfect pangram.
Can I see which letters are missing?
The tool shows all letters that appear in your text. To find missing letters, compare the output against the full alphabet — any letter not listed is absent from your text.
