About this tool

Every code point in your text is counted and classified — letters, digits, whitespace, punctuation, symbols, emoji and other Unicode — with counts, percentages, a sortable bar chart, digram and trigram tables, and the Shannon entropy of the distribution in bits per character.

A separate pass finds which letters start and end words, and the letter distribution is compared with standard English frequencies. Enable the second text box to compare two distributions side by side, or export everything to CSV. Analysis is capped at 300 rows per table so very large documents stay responsive, and everything runs in your browser.
