Frequently Asked Questions — Palindrome Checker
What is a palindrome?
A palindrome is a word, phrase, number, or sequence that reads the same forwards and backwards. Simple examples include "racecar," "madam," and "level." Phrase palindromes like "A man, a plan, a canal, Panama" also qualify when spaces and punctuation are ignored.
Does the checker ignore spaces and punctuation?
Yes. By default, the checker strips spaces, punctuation, and special characters before comparing, so "Was it a car or a cat I saw?" is correctly identified as a palindrome. You can disable this to check strict character-by-character palindromes.
Can I check numbers for palindromes?
Yes. Numeric palindromes like 12321, 1001, and 45654 are all correctly identified. The tool treats the input as a string so it works with both text and numeric palindromes equally well.
