## About

A palindrome is a word, phrase, number, or sequence of characters that reads the same forward and backward (ignoring spaces, punctuation, and case). "racecar", "level", and "A man, a plan, a canal: Panama" are all palindromes.

Type or paste any text and the tool tells you whether it is a palindrome, plus the cleaned-up form it is comparing. Use it for puzzles, words games, or just for fun.

## How to use

1. **Paste your text** — A word, phrase, or full sentence.
2. **Read the result** — "Yes, palindrome" or "Not a palindrome" plus the normalized form.

## Examples

### "A man, a plan, a canal: Panama"

One of the most famous palindromic sentences.

Output:

```
Yes — palindrome
```

### "racecar"

A simple single-word palindrome.

Output:

```
Yes — palindrome
```

## FAQ

### What is an anagram?

An anagram is a word or phrase formed by rearranging the letters of another. "listen" and "silent" are anagrams. The tool can also tell you whether two inputs are anagrams of each other.

### What is ignored when checking?

Case (A = a), spaces, and punctuation. The comparison is on letters and digits only. This matches the conventional definition of a palindrome for word games.

### Are spaces and punctuation ignored?

Yes, by default. "A man, a plan, a canal: Panama" is a palindrome if you strip the punctuation and case-fold. There is a toggle to do a strict character-by-character check if you want.

### Does it support Unicode palindromes?

Yes. The tool normalizes Unicode combining marks and case before comparison, so words like "A̐a̐" (with combining characters) or "ÀÁ" are detected as palindromes. Emoji and surrogate pairs are also handled.
