Oikogen

A private family tree you build by telling your family's story

Type or say what you know, such as “My grandmother Rose grew up in Cork. She married my grandad Tom in 1952,” and Oikogen turns it into a family tree. Nothing goes into your family tree until you check it, and your family data never leaves your device.

Free while in beta, no credit card needed. No account, no sign-up.

You say

My grandmother Rose grew up in Cork. She married my grandad Tom in 1952.

Oikogen asks you to check

  • Rose, your grandmother. Grew up in Cork.
  • Tom, your grandfather. Married Rose in 1952.

Save it, fix it, or discard it. Then the tree grows.

A family tree app that listens

Talk instead of filling in forms

Tell your family's story in your own words, in any order: “my dad's sister June,” “Grandpa worked on the railways.” Oikogen works out who's who and where they go on the tree.

Check before anything is saved

Each message becomes a card of new people and facts, and nothing from it goes into your family until you save it. Every fact remembers the sentence it came from, and when two sources disagree, Oikogen tells you.

Private by design

Oikogen runs in your web browser. There's no account to create, and your family data never leaves your device. How privacy works.

What you can do with it

Built from your family's own stories

Oikogen works from what you and your family tell it: names, places, dates and the stories behind them. It keeps track of who said what, which makes it a home for the stories that aren't written down anywhere else.

What you need


Start with one sentence

Tell it who your grandparents were. That's enough to begin.
