Palindrome checker

Client

See whether text reads the same forward and backward. For character reversal without checking, try reverse text.

What counts as a palindrome

A palindrome reads the same forward and backward after you choose whether to ignore case and strip punctuation. This page compares code units in the browser—it is not a grapheme-cluster palindrome checker for every emoji sequence.

  • Quick classroom demo of normalized palindrome rules.
  • Unit-test sample strings before shipping word-game features.

Common mistakes to avoid

  • Expecting emoji-aware palindromes

    Comparison uses JavaScript string code units, not full grapheme clusters.

  • Leaving punctuation in strict mode

    Turn on letters-and-digits-only to ignore spaces and symbols like classic phrase checks.
