🔄 Palindrome Checker

About this Checker

The WRDNWRD Palindrome Checker instantly analyzes any word, phrase, or sentence to determine if it reads the same backward and forward. It ignores spaces, punctuation, symbols, and letter casing — focusing only on the actual sequence of characters. For example, "A man, a plan, a canal — Panama" is normalized as amanaplanacanalpanama before comparison.

Examples

• Input: racecar → ✅ Palindrome
• Input: A man, a plan, a canal — Panama → ✅ Palindrome
• Input: hello → ❌ Not a palindrome

How it works

The checker converts your text to lowercase, removes any non-alphanumeric characters, and then reverses the sequence. If the cleaned version matches its reverse, it’s a palindrome. This method works for both single words and entire sentences.

Notes

• Works with words and numbers from multiple languages (Unicode-aware).
• Maximum input length is 5,000 characters for performance and accuracy.
