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.

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