What this tool is for
A palindrome reads the same forwards and backwards. "A man, a plan, a canal, Panama" qualifies once you drop the spaces and punctuation, which is exactly what this checker does before comparing, and it shows you the normalised text so the verdict is never a black box.
How to use it
- Type or paste the word, phrase or number.
- Read the verdict and the normalised comparison below it.
Frequently asked questions
Do spaces and punctuation matter?
Not by default: they are stripped before comparing, which is the usual convention for phrase palindromes. Turn on strict mode to compare the text exactly as typed.
