AES Encryption Explained: How It Works and Why It Matters

Check if text reads the same forwards and backwards. Find palindromic substrings and analyze character symmetry.
A Palindrome Checker is a tool that determines whether a given string reads the same forwards and backwards. Palindromes can be single words like "radar" or "level", phrases like "A man, a plan, a canal: Panama", or even numbers like 12321.
Beyond simple checking, this tool can also find all palindromic substrings within text, analyze each word individually, and provide detailed character-level symmetry analysis — making it useful for linguistics, puzzles, coding challenges, and educational purposes.
A palindrome is a word, phrase, number, or sequence that reads the same forwards and backwards. Examples include "racecar", "madam", and "12321".
You can toggle case sensitivity. By default, case is ignored so "Racecar" is still detected as a palindrome. Enable case sensitivity for strict matching.
These are sequences within a longer string that are themselves palindromes. For example, in "banana", the substrings "ana" and "anana" are palindromes.
