About Palindrome Checker
A palindrome reads the same forwards and backwards. Whether a phrase qualifies depends on how strictly you apply the definition — 'racecar' is obviously a palindrome, but 'A man a plan a canal Panama' only qualifies if you ignore case, spaces, and punctuation. This checker lets you control all three with checkboxes: Ignore case (lowercases before comparison), Ignore spaces (strips all whitespace), and Ignore punctuation (removes all non-alphanumeric characters). The cleaned string is shown below the result so you can see exactly what was compared. The result is displayed as a large green 'Palindrome!' or red 'Not a palindrome' card that updates instantly as you type. Useful for word games, linguistics exercises, and testing string manipulation logic.
