Analyze character and word frequency in any text
Character Frequency Counter breaks your text down into two sortable tables: one showing how often every individual character appears, and another showing how often each distinct word appears. Both include raw counts and percentages, so you can instantly see the composition of a passage — its most common letters, its most-used vocabulary, and the overall balance of the writing. Paste your text and the analysis updates immediately, no configuration required.
Frequency analysis is a surprisingly versatile technique. Writers use it to catch overused words and diversify their vocabulary, editors use it to spot crutch phrases, and students use it to study the texture of a text. It is also the foundation of classical cryptography: because letter frequencies in a language are remarkably stable, counting characters is the first step to cracking simple substitution ciphers, a favorite exercise for puzzle enthusiasts and computer science learners.
You control how the analysis treats your text with options to include or exclude whitespace and to fold letter case together, so "The" and "the" count as the same word for a cleaner picture. Sort either table by frequency to surface the most common items or alphabetically for quick lookup. Everything runs locally in your browser, keeping your content private, and results can be copied for reports, research notes or further processing.
