What is Palindrome Checker?
A palindrome is a word, phrase, or sequence that reads the same forwards and backwards when you ignore spaces, punctuation, and letter case.
Famous examples include 'racecar', 'A man a plan a canal Panama', and 'Was it a car or a cat I saw'. Palindrome checking is useful for word games, programming challenges, linguistics research, and educational exercises. This tool strips all non-alphanumeric characters and converts to lowercase before comparing, so it correctly identifies sentence-level palindromes that would not be obvious at first glance. The side-by-side comparison lets you see exactly where forward and reversed text match or differ.
