Text Reverser

Take the sentence time flies fast as a worked example. Reversing every character gives tsaf seilf emit. Reversing the letters inside each word gives emit seilf tsaf, with the words still in their original places. Reversing the word order gives fast flies time, perfectly readable but backwards in meaning. Line-order reversal leaves a single line unchanged.

A palindrome reads the same in both directions, and reversing a candidate is the quickest way to test one. The catch is punctuation and spacing. Never odd or even comes back as neve ro ddo reveN, which does not match, yet strip the spaces and the letters mirror perfectly. Traditional palindromes ignore spaces, capitals and punctuation.

So when you test a phrase, compare the letters rather than the raw output. This tool reverses exactly what you give it, including spaces and punctuation, because that is what the other three modes need. Remove the spaces yourself first if you want a strict palindrome check, and the comparison becomes obvious at a glance.

Reversed characters are still ordinary characters, so the result stays searchable and anyone can reverse it back in a second. It hides nothing and encodes nothing. Treat it as a visual effect or a puzzle device rather than a form of obfuscation, and never as a way to slip text past a moderation filter.

Right-to-left scripts such as Arabic and Hebrew are a separate case. They are already stored in logical order and displayed right to left by the browser, so reversing the characters scrambles them rather than mirroring them. Emoji and accented letters are handled as single units, so a flag or a diacritic survives the flip intact.
