A palindrome is a word or phrase that reads the same whether you read it forwards or backwards — like "racecar", "A man, a plan, a canal: Panama", or "Was it a car or a cat I saw?".

How It Works

The text is normalized by converting to lowercase and removing all non-alphanumeric characters (spaces, punctuation, etc.). The normalized string is compared to its reverse. If they're identical, it's a palindrome. The tool also shows where the first difference occurs if it's not a palindrome.
