A strict character-for-character comparison fails almost every famous palindrome. “A man, a plan, a canal: Panama” has spaces, commas, and a colon in it — none of which belong in the actual comparison.
Our new palindrome checker does it the right way:
- Normalizes before comparing — lowercases the text, strips accents down to their base letters, and removes everything that isn’t a letter or number.
- Emoji-safe reversal — built on a code-point-safe method, so multi-byte characters never get scrambled mid-comparison.
- A clear verdict — plus the cleaned string and character count, so you can see exactly what was compared.
- Three example chips — click “racecar” or the full “Was it a car or a cat I saw” to see it in action instantly.
Numbers count too: “12321” and “2002” both check out as palindromes.
Type a short phrase and the result syncs to the URL, so you can share a link straight to a specific check — the one deliberate exception to this hub’s rule of keeping user text out of URLs, since a short phrase isn’t private the way a pasted paragraph is.
