How is a palindrome detected?

The text is normalised with your chosen options and compared to its reverse character by character.

Do spaces and punctuation count?

Only if you turn off the ignore options; by default case, spaces, and punctuation are ignored.

Why is my anagram check failing?

Open the character balance panel — it lists exactly which characters appear a different number of times in each text.

Is my data uploaded to a server?

No. This tool runs entirely in your browser using standard web APIs, so your input never leaves your device and nothing is logged or stored on our servers.

Does it work offline and on mobile?

Yes. Once the page has loaded it keeps working without a network connection, and the layout is responsive so it stays usable on phones and tablets.
