Palindrome Checker
Check if any word, phrase, or number reads the same forwards and backwards.
'A man, a plan, a canal: Panama' only works as a palindrome once the comma, the colon, the spaces, and the case differences all get stripped away first, since a literal character-by-character reversal of the raw text would treat those as real differences and wrongly call a genuine phrase-level palindrome not one. This tool checks whether a word, a phrase, or a number reads the same forwards and backwards, normalizing punctuation, spacing, and case before comparing rather than reversing the raw text as typed.

Useful for checking whether a full phrase is a genuine palindrome once punctuation and spacing are properly ignored, verifying a number reads the same both directions for a puzzle or a specific numeric property, or confirming a single word is a true palindrome without manually stripping formatting first.
