About this tool

A palindrome reads the same in both directions, and the famous examples hide their symmetry behind spaces and punctuation. This checker strips those away, lowercases the text and compares it with its reverse to give an instant verdict.

It works for single words, long phrases and numbers alike, and shows the cleaned-up form so you can see exactly what was compared. Great for word games, puzzles and curiosity. Everything runs in your browser.

Frequently asked questions

What counts as a palindrome?

Text that reads the same forwards and backwards once spaces, punctuation and capitalisation are stripped — so “A man, a plan, a canal: Panama” qualifies.

Does it work for numbers?

Yes. Digits are treated like any other character, so 12321 is recognised as a palindrome.
