The tool normalizes your input the same way, then compares it against its own reverse character by character.
Numbers work too: 12321 is a palindrome while 12345 is not. Single letters and empty-meaning inputs are edge cases, a single character trivially reads the same both ways.
The reversed-text box shows your exact input flipped, useful for spotting where a near-palindrome breaks.
