An interactive canvas with zoom, pan, and fit-to-screen navigation. Add people, relationships, dates, and photos — then click any node to open a full detail drawer. Private by default, single unified tree per account.
Add as many family members as you need. No tree size limits on paid plans. Add relationships with two taps — parent, child, spouse, sibling. AncestorOS handles the structure so you can focus on the people.
Each person node shows their avatar (or initials), name in serif, and birth–death years right on the canvas. Click any node and a side drawer opens with full profile details — including an Edit button, View Detail link, and sibling chips. Tap a sibling chip to highlight that person with a gold border and glow animation, making family relationships instantly visible.
Your tree is yours alone. Nothing is shared to a public network. No crowdsourcing your family data to strangers. AncestorOS is built around a single unified tree per account — no juggling multiple trees — so all your research stays in one coherent place.
Start with yourself and grow at your own pace. There is no right order, no required fields, and no deadline.
Create your own profile with your name, birth date, and birthplace. This becomes the root of your tree. You can always add more detail later.
Work backwards one generation at a time. Add names, dates, and places as you know them. Leave unknowns blank — you can fill them in later as you research.
Branches expand naturally. Add siblings, their spouses, their children. The tree grows with you over months and years of research.
Built for real genealogists — hobbyists and professionals alike.
No caps on paid plans. Add every cousin, great-grandparent, and distant relative you discover.
Click any sibling chip in the detail drawer to highlight that family member with a gold border and glow — instantly see who shares the same parents.
Cite every fact. Attach sources to births, marriages, deaths, and events. Professional-grade documentation built in.
Full functionality on iOS and Android browsers. Add a person at a family reunion, right from your phone.
Search by name from the tree canvas. A dropdown shows matching people with avatars — select one to jump directly to that node.
Export your entire tree as a standard .ged file at any time. Use it in any other genealogy software — no lock-in.
