The collaborative family tree
Every family,
one tree.
Add the parents, partners, and children you know — Nostari deduces everything else, from half-siblings to second cousins once removed. And when someone else's tree describes your grandmother too, the trees join, and long-lost relatives find each other.
Takes about two minutes. Start with just yourself.
One shared tree
Every person is a wiki page anyone in the family can improve — dates, places, stories, photos — with a full history of every change, so nothing is ever lost.
Name any relationship
Pick any two people and the kinship engine names how they relate — “your second cousin once removed” — and shows the chain of people that connects you.
Find lost relatives
When two trees describe the same person, Nostari notices and proposes joining them — two families discovering they were one all along.
How it works
Start with yourself
Create your own profile — the first leaf on the tree.
Add the family you know
Parents, grandparents, siblings, cousins. Everyone can pitch in.
Watch trees connect
Nostari spots shared ancestors and joins branches across families.
Your family stays yours. Everything you add is visible only to signed-in family members — details about living people are never public.
