Frequently Asked Questions
What is a palindrome?
A palindrome is a word, phrase, number or sequence that reads the same forwards and backwards. English examples include "racecar", "level" and the sentence "Was it a car or a cat I saw?".
Does it ignore spaces and punctuation?
By default, yes. With "ignore punctuation" turned on, spaces, commas and other symbols are removed before checking, so "A man, a plan, a canal: Panama" counts as a palindrome. Turn the option off to require an exact match.
Is the checker case-sensitive?
Only if you want it to be. With "ignore case" turned on (the default), "Anna" is treated the same as "anna". Turn it off to make capitalisation matter.
Can it check numbers?
Yes. Numbers are treated as text, so 12321 is a palindrome while 12345 is not. This makes it handy for checking palindromic numbers and dates.
