Check if text is a palindrome
Check whether a word, phrase, or number reads the same forwards and backwards.
Enter some text to check whether it's a palindrome.
Try single words like "racecar" or full phrases like "A man, a plan, a canal: Panama".
Only letters and digits are compared, so phrases with natural spacing and punctuation still work.
See instantly whether it's a palindrome, plus the exact normalized string that was compared.
Frequently asked
What counts as a palindrome here?
Any text that reads the same forwards and backwards once you lowercase it and ignore spaces, punctuation, and symbols. So "Never odd or even" and "12321" both count.
Why does the tool show a "normalized" version of my text?
It's exactly what was compared (your input with casing, spaces, and punctuation stripped out) so you can see precisely why something was or wasn't judged a palindrome.
Does it work with numbers as well as words?
Yes. Digits are treated the same as letters, so numeric palindromes like "12321" or mixed strings like "A1B2B1A" are checked correctly.
What happens if I leave the field empty?
No verdict is shown for empty input. The tool waits until there's actual text to evaluate.
