Palindrome Checker
Check whether a word or phrase reads the same forwards and backwards. Free and private, right in your browser.
Type or paste any word, name, or phrase and instantly see whether it reads the same forwards and backwards. It ignores spaces, punctuation, and capitalization, so it catches phrase-level palindromes like "A man, a plan, a canal, Panama", not just single words like "racecar."
How to use it
- Type or paste your text into the box
- Watch the result update as you type
- Toggle strict mode if you only want exact letter-for-letter matches
Frequently asked questions
- Does it ignore spaces and punctuation?
- Yes, by default it strips spaces, commas, apostrophes, and other punctuation and ignores case, so "Was it a car or a cat I saw?" checks correctly. You can switch to strict mode if you want an exact character-by-character comparison instead.
- Does it work with numbers, like 12321?
- Yes, it checks any sequence of characters, so numeric palindromes work exactly the same as word or phrase palindromes.
- Is my text sent anywhere?
- No, the check runs entirely in your browser using simple string comparison, so nothing you type ever leaves your device.
