FAQ

Is my list saved automatically?
Names and results stay in the current page memory and clear on reload. Sharing includes only the tool link, never the list or results.
What happens to duplicate names?
Duplicates are flagged, but each input row remains an entry. No repeats refers to rows, so matching text or people may still appear.
