Palindrome Checker

A palindrome reads the same forwards and backwards. This checker applies the standard convention: spaces, punctuation and capitalisation are ignored, so 'A man, a plan, a canal: Panama' correctly registers as a palindrome.

What the Palindrome Checker does

The result shows its working — the cleaned string and its reverse are both displayed alongside the verdict, so when something is not a palindrome you can see exactly where the two diverge.

How it works

Using the Palindrome Checker

  1. 1Type or paste a word, phrase or sentence.
  2. 2Everything except letters and digits is removed.
  3. 3The remaining text is lowercased so capitalisation cannot affect the result.
  4. 4The cleaned string is compared with its own reverse.
  5. 5The verdict is shown along with both strings for comparison.
