Check your family tree before you import it.

Drop a GEDCOM export and see what Gramps, webtrees, RootsMagic or Geneanet will make of it: broken links, cut-off names, mangled notes, places that will never match anything. Then apply the repairs that are provably safe. Everything runs in this tab.

• Your file never leaves this browser. It is read, checked and repaired locally; there is no server on the other end.
• You can verify that in five seconds. This page ships a Content-Security-Policy that forbids every network connection. Open your devtools Network tab: it stays empty while you work.
• No account, no cookies, no analytics.
• What you download carries no record content. A saved baseline holds rule codes, counts and digests; the repaired file is the only download that contains your tree.
