Forwards and backwards
A palindrome reads the same in both directions: “racecar”, “12321”, or whole sentences like “A man, a plan, a canal: Panama”. The checker normalises your text the way puzzle makers do — ignoring capitals, spaces, punctuation and accents — and shows the cleaned text next to its reverse so you can see why the answer is yes or no.
If it isn't a palindrome, you'll see the longest palindrome hidden inside it. Works with numbers and non-English scripts too.

Frequently asked questions
What is a palindrome?
A word, phrase, number or sequence that reads the same backwards as forwards, such as “level” or 1221.
Do spaces and punctuation count?
Usually not. The default settings ignore them, as in classic palindrome sentences.
Are numbers palindromes too?
Yes — 121, 12321 and 1001 are palindromic numbers.
