See exactly what your text is made of
Counting how often each character appears turns a block of text into a distribution: which letters dominate, how many spaces and punctuation marks there are, whether an unexpected symbol is hiding in the data. This tool tallies every character, letter and symbol and shows the counts, so you can inspect the composition of the text rather than guessing.
Useful well beyond curiosity
A frequency count answers real questions. It reveals a stray non-breaking space or invisible character that is breaking a match. It confirms whether a supposedly clean field really contains only digits. It is the starting point for simple cryptography puzzles, where letter frequency is the first clue to a substitution cipher. And it gives a quick sense of a text’s makeup for linguistics or word games.
Counts characters, not just letters
The count includes everything: letters, digits, spaces, punctuation and symbols, because the characters you did not expect are usually the ones worth finding. Seeing the full inventory is how you catch the tab that should have been a space or the smart quote that should have been straight. The analysis runs entirely in your browser, so even private text stays on your machine.

Frequently Asked Questions
Does it count spaces and punctuation?
Yes. Every character is counted, including spaces, tabs, punctuation and symbols, not just letters, because the unexpected characters are often the ones you need to find.
Is it case-sensitive?
It counts each distinct character, so upper and lower case letters are tallied separately, which is usually what you want when inspecting composition.
What is this useful for?
Spotting stray or invisible characters, verifying a field contains only expected characters, solving substitution-cipher puzzles, and analysing text composition.
Can it find invisible characters?
Yes. Because it counts every character, a zero-width or non-breaking space shows up in the tally even though you cannot see it in the text.
Is my text uploaded?
No. The counting runs entirely in your browser.
