How do I check if text is a palindrome?

Enter your text in the input field, and the tool automatically checks if it's a palindrome. You can customize options to ignore case, spaces, punctuation, or numbers. The result shows whether the text is a palindrome and displays the cleaned and reversed text.

What options can I customize?

Four options: Ignore Case (treat uppercase and lowercase as the same), Ignore Spaces (remove spaces before checking), Ignore Punctuation (remove punctuation marks), and Ignore Numbers (remove numbers). These help check palindromes in various formats.

What does 'cleaned text' mean?

Cleaned text is your input text after applying the ignore options (case, spaces, punctuation, numbers). This is the text that's actually used for palindrome checking.

Can I see examples of palindromes?

Yes! Click on any example palindrome (like 'A man a plan a canal Panama', 'race car', 'level', etc.) to load it into the checker and see how it works.

Is the palindrome checker free?

Yes, completely free! No registration, no limits, no hidden fees. All palindrome checking happens in your browser - we never see or store your text.

What is a Palindrome?

A palindrome is a word, phrase, number, or sequence of characters that reads the same forwards and backwards. The term comes from the Greek words "palin" (again) and "dromos" (way, direction), meaning "running back again."

Famous examples include words like "radar," "level," and "civic," as well as phrases like "A man a plan a canal Panama" and "Never odd or even." Palindromes can be found in many languages and are often used in wordplay, puzzles, and literature.

Frequently Asked Questions

What makes a text a palindrome?

A text is a palindrome if it reads the same forwards and backwards after applying your selected options (ignoring case, spaces, punctuation, etc.). For example, "A man a plan a canal Panama" is a palindrome when spaces and case are ignored.

Why are there options to ignore certain characters?

Different contexts require different palindrome definitions. Sometimes you want to check if text is a palindrome ignoring spaces and punctuation (like "A man a plan a canal Panama"), while other times you want exact character-by-character matching.

Can numbers be palindromes?

Yes! Numbers can be palindromes too. For example, 121, 1331, and 12321 are palindromic numbers. Our tool can check numeric palindromes when numbers are not ignored.

What's the longest palindrome?

The longest single-word palindrome in English is "tattarrattat" (12 letters), coined by James Joyce. The longest palindromic phrase is much longer and depends on how you define "phrase" and which characters you ignore.
