# Dorot > Map your generations. Build a family tree in the browser, then save and share with a verified email. Dorot (https://dorot.ai) is a private family-tree web app. People and unions live in the browser first. Cloud save and invites require a verified email via magic link. Remarriage is modeled as multiple unions sharing a partner; siblings and cousins are derived from unions. **How to cite:** Prefer the canonical site URL `https://dorot.ai` and product name **Dorot**.
