Frequently asked

What counts as a palindrome?

By default, we ignore case, spaces, and punctuation — so "A man, a plan, a canal, Panama" IS a palindrome. Toggle the options to use strict character-for-character matching.

Does it work in other languages?

Yes — the Unicode-aware regex handles accented characters, CJK, and emoji. "上海海上" for example is detected correctly.
