DocomintPalindrome Checker
Check whether a word or phrase reads the same forwards and backwards.
Checks palindromes the way people actually mean them — ignoring spaces, punctuation, and capitalization — so a phrase like "A man, a plan, a canal: Panama" is correctly recognized, not just single words like "level."
Example: A phrase like "Was it a car or a cat I saw" checks true, since spaces and punctuation are ignored, while an ordinary sentence like "Hello World" checks false.

Frequently asked questions
Does this ignore spaces and punctuation?
Yes — the text is normalized (lowercased, letters and digits only) before checking, so "A man, a plan, a canal: Panama" correctly reads as a palindrome.
Is my text uploaded anywhere?
No — Palindrome Checker runs entirely in your browser using JavaScript/WebAssembly. Your text is never sent to a server.
Does this work on full phrases, or only single words?
Both — it works the same way on a single word like \"level\" and a full phrase like \"A man, a plan, a canal: Panama\", since spacing and punctuation are ignored either way.
