Kostenloser Buchstaben- und Zeichenfrequenz-Zähler. Zeigt Anzahl und Prozent jedes Buchstabens, mit Vergleich zu erwarteten englischen Häufigkeiten (E ~12,7%, T ~9,3%).
Use the letter frequency analyzer for cryptography puzzles (frequency analysis is the classic substitution-cipher attack), Wordle / Scrabble strategy, linguistic teaching, or for detecting unusual content distributions.
Letter frequency is character-level analysis; Word Frequency is word-level. The two reveal very different things — letter frequency exposes the language; word frequency exposes the content.
Each character in the text is counted. The tool reports counts and percentages, sorted by frequency.
For English baseline mode, the table includes expected frequencies (E ~12.7%, T ~9.3%, A ~8.0%) and the deviation.
Letters with disproportionately high deviations may indicate non-English text, technical vocabulary, or unusual content.
Cryptography (breaking substitution ciphers), Wordle/Scrabble strategy, linguistic teaching, content-type detection.
English letter frequencies are stable (E ~12.7%, T ~9.3%, A ~8.0%). Deviations from baseline suggest unusual content or non-English text.
Off by default — punctuation and digits can swamp letter counts. Toggle on for a complete character analysis.

E: 12.4% (expected 12.7%) · T: 9.0% (9.3%) · A: 8.5% (8.0%) — normal English distribution.
English letter frequencies are remarkably consistent: E is always around 12-13%, T around 9%, A around 8%. Deviations suggest unusual content (technical jargon, proper nouns, or non-English text).
