How it works
Paste your text and pick a scramble mode: the text scrambler shuffles the letters inside each word, the order of the words, the sentences, the lines, or every single character. The default mode is the classic typoglycemia trick — it keeps the first and last letter of every word and shuffles only the middle, so the text stays surprisingly readable while looking completely jumbled. Punctuation, spacing and line breaks stay exactly where they were, sentence mode keeps your paragraphs apart, and "Keep original capitalization" restores the original upper/lowercase pattern.
Press "Scramble again" whenever you want a different jumble. Every jumble is driven by the puzzle number under Advanced, so the same text plus the same number always produces the same result — handy for puzzles, worksheets and word games you need to reproduce later. The shuffling is plain JavaScript running in your browser (a seeded Fisher–Yates shuffle); nothing you type is uploaded, logged or stored anywhere.
Frequently asked questions
How do you scramble text online?
Paste your text into the box, choose a scramble mode (letters inside each word, all letters in a word, word order, sentence order, line order, or every character) and the scrambled version appears instantly. Then copy it or download it as a .txt file. Everything happens in your browser, so nothing is uploaded.
What is typoglycemia, and why is the scrambled text still readable?
Typoglycemia is the effect where a word stays recognisable as long as its first and last letters are unchanged, because we read word shapes rather than letter by letter. The default mode of this letter scrambler keeps the first and last letter of every word and shuffles only the middle, so the text looks jumbled but most people can still read it.
Can scrambled text be unscrambled?
Not automatically. The shuffle throws away the original letter order, so there is no reverse button. What you can do is reproduce a jumble exactly: every scramble is driven by the seed number, so the same text plus the same seed always gives the same result. Note the seed (or keep your original text) if you need that output again later.
