About this tool
Check whether a word, phrase or number reads the same forwards and backwards, ignoring case and punctuation.
Palindrome Checker is part of the TmpMailer Text & Writing set — free browser utilities that open instantly, need no account, and pair well with a temporary-email workflow when you just need a quick result.
Common use cases
- Checking a puzzle answer.
- Teaching string normalisation.
- Validating a palindromic test input.
Common questions
Are spaces and punctuation ignored?
Yes. The checker normalises the text before comparing, which is the usual definition for phrases.
Do accented letters work?
They are compared as written. Transliterate first if you want accent-insensitive matching.
Is a single letter a palindrome?
Yes, trivially. Empty input is not treated as a valid test.
