About the Palindrome & Anagram Checker
Checks whether text reads the same forwards and backwards (a palindrome) ignoring spaces and punctuation, and separately checks whether two words or phrases are anagrams of each other.
How to use it
- For a palindrome check: enter Text in the first section.
- For an anagram check: enter two words or phrases in the second section.
- Read the result in each section's readout.
Formula
Palindrome check: normalized text (lowercase, letters/numbers only) must equal its own reverse. Anagram check: both texts, normalized and sorted alphabetically, must produce identical character sequences.
Worked example
"A man a plan a canal Panama" is a palindrome once spaces and capitalization are ignored. "listen" and "silent" are anagrams, sharing exactly the same six letters.
Recommendations
- • Both checks ignore spaces, punctuation, and capitalization, so phrases work as naturally as single words.
- • For anagrams, word order and spacing don't matter — only the exact multiset of letters counts.
- • Numbers can form palindromes too, like 12321, following the same reversal logic as text.
Frequently asked questions
No — both are stripped before comparison, which is why phrases work despite containing spaces and capital letters.
