Frequently asked questions
What counts as a palindrome?
A palindrome reads the same forwards and backwards, like 'racecar' or '12321'. With the default settings, case, spaces, and punctuation are ignored so phrases like 'A man, a plan, a canal: Panama' also count.
Can I make the check strict?
Yes. Turn off 'ignore case', 'ignore spaces', or 'ignore punctuation' to require an exact reverse, character for character.
Is an empty box a palindrome?
Yes. An empty string, or one with only spaces and punctuation that get stripped, reads the same both ways, so the tool reports it as a palindrome.
Does it work with numbers and other languages?
Yes. Numbers like '12321' work, and accented or non-Latin letters and emoji are handled without breaking characters apart.
Is my text private?
Yes. The check runs entirely in your browser. Nothing you type is uploaded or stored anywhere.
