How do you check if a string is a palindrome?

A palindrome string checker tests whether text reads the same forwards and backwards. Snabbit ignores spaces, punctuation and capitalisation, then compares the cleaned text with its reverse and reports Yes or No with a short reason. So “A man, a plan, a canal: Panama” passes. It runs in your browser, keeping whatever you check private.

How to use the Palindrome Checker

  1. 1 Paste the word, phrase or string you want to test.
  2. 2 The verdict appears instantly: Yes or No.
  3. 3 Read the explanation to see the cleaned forwards and backwards forms.
  4. 4 Adjust the text and re-check as needed.

What you can use it for

  • Verifying a palindrome you wrote by hand.
  • Checking numeric palindromes like dates or IDs.
  • Teaching the palindrome concept with live feedback.
  • Testing edge cases for a coding exercise.

Frequently asked questions

Does it ignore spaces and punctuation?
Yes. The checker strips everything except letters and digits and lowercases the result before comparing, so phrases like “Was it a car or a cat I saw?” are recognised as palindromes.
Why does it show the reversed text?
Showing the cleaned forwards and backwards forms makes the verdict transparent — you can see exactly where a near-palindrome breaks down.
Are numbers treated as palindromes too?
Yes. Digits are kept during the comparison, so numeric strings like “12321” are correctly reported as palindromes.
