Checks whether text reads the same forwards and backwards (ignoring case and punctuation). Paste your text on the left and NMSnabbit instantly shows the result on the right. For example, “racecar” gives “Yes, palindrome”. Everything runs locally in your browser — nothing is uploaded, so it stays private and works offline. You can process several values at once and copy the result with one click.
