What this tool does
A palindrome reads the same forwards and backwards once you ignore spacing, punctuation and letter case — 'A man, a plan, a canal: Panama' is one, 'hello' isn't. This tool normalizes your text the same way and shows the comparison string it used, so you can see exactly why something did or didn't match. Switch to Each line to check a whole list of words or phrases at once, handy for word-game lists or homework checks.
How to use it
- Paste a phrase, or switch to Each line and paste a list.
- Read the Palindrome / Not a palindrome result for each entry.
- Check the normalized text shown underneath to see what was actually compared.

Frequently asked questions
- Does capitalization matter?
- No. Letters are lowercased before comparison, so 'Racecar' and 'racecar' are treated the same.
- Are spaces and punctuation ignored?
- Yes. Only letters and digits are kept for the comparison, so phrases like 'A man, a plan, a canal: Panama' are checked as 'amanaplanacanalpanama'.
- Can I check a whole list at once?
- Yes. Switch to Each line mode and paste one word or phrase per line; every line is checked independently and listed with its own result.
