Palindrome Checker
Type a word or phrase and find out instantly whether it reads the same backwards.
📖 How it works & FAQWhat is a palindrome?
A palindrome is a word, phrase, number or sequence that reads exactly the same forwards and backwards. Classic single words include level, radar, civic and kayak. Longer phrase palindromes like “A man, a plan, a canal, Panama” or “Was it a car or a cat I saw?” only work once you strip out the spaces, commas, question marks and capital letters. That is exactly what this checker does for you.
How this checker decides
The tool first cleans your text: it lowercases every letter and removes everything that isn’t a letter or a number — spaces, punctuation, apostrophes and symbols all disappear. It then reverses that cleaned string and compares it to the original cleaned version. If the two match character for character, you have a palindrome. Showing both the cleaned and reversed strings lets you see precisely what was compared, so there are no surprises.
How to use it
- Type or paste a word, phrase, or sentence into the box above.
- Read the big result banner — a green YES means it’s a palindrome, a red NO means it isn’t.
- Check the Cleaned line to see the letters and numbers that were actually compared.
- Compare it against the Cleaned, reversed line — when they’re identical, it’s a palindrome.
- Edit your text and the result updates instantly as you type.
FAQ
- Does capitalization or punctuation matter?
- No. The checker ignores letter case, spaces and all punctuation, so “Madam, I’m Adam” counts as a palindrome.
- Do numbers count?
- Yes. Digits are kept and checked, so 12321 reads as a palindrome while 12345 does not.
- Is my text uploaded anywhere?
- No. Everything runs privately in your browser — nothing you type is sent to a server or stored.
- Can it handle full sentences?
- Absolutely. Paste an entire phrase and the tool strips the spaces and punctuation before checking it end to end.
