Text Scrambler
A text scrambler shuffles the inner letters of every word while pinning the first and last letters in place — and the result usually stays readable. That is the well-known typoglycemia effect: we recognize words largely by their outer letters and overall shape, so scrambled middles barely slow a fluent reader down. Paste any text and each word of four or more letters gets its middle letters shuffled; punctuation, spacing, and capitalization stay where they were. Words of three letters or fewer pass through untouched, since they have no middle to scramble. Expect some words to come back unchanged — a four-letter word has only two inner letters, so half the time the shuffle lands on the original — and expect long or unfamiliar words to be genuinely hard to decode, since the effect leans on context and familiarity. It makes a great five-minute classroom demo: scramble a short paragraph, have students read it aloud, and discuss why they still can.

FAQ
why is scrambled text still readable
Because we recognize words by their overall shape and their first and last letters, not by reading each letter in order. As long as the outer letters stay put, the brain fills in the scrambled middle almost automatically — an effect often called typoglycemia.
how does the scrambler work
It keeps the first and last letter of each word in place and shuffles only the letters in between. Words of three letters or fewer are left unchanged, since there are no inner letters to scramble without altering the recognizable outline.
why do some words come back unchanged
Words of three letters or fewer are skipped entirely — with the first and last letters pinned there is nothing left to move. Four-letter words have just two inner letters, so the shuffle lands back on the original about half the time. Only at five or more letters does every word reliably look scrambled.
can scrambled text be used in a classroom exercise
It works well as a quick activity: paste a short paragraph, scramble it, and ask students to read it aloud. Most are surprised how fluently they read text that looks chaotic, which opens a discussion about word-shape recognition versus letter-by-letter decoding. Keep passages to a few sentences so the novelty carries the activity.
