A family tree that lives online and keeps every source
Build your family tree with the evidence beside it. Keep sources and uncertain dates, explore connections, and turn unanswered questions into research tasks — on your own or with family.
- Free · no card · no expiry
- Your GEDCOM comes in, and goes back out
- Export is always free

Ask any fact where it came from
Attach the scan, name the register, and say how sure you are — high, medium or low, recorded on the fact rather than on the source. One register can support a baptism at high confidence and an occupation at low, and Leaves keeps both instead of averaging them.
How sources and citations workAbout 1850 stays about 1850
Record an exact day, an approximate date, a range, a period or the words the source used. The qualifier stays visible in records and timelines, so about 1850 never quietly becomes 1 January 1850.
What Leaves does with an uncertain dateBring in the cousin with the shoebox
Invite family by email with their own accounts. Free includes two viewer collaborators, so relatives can follow your research in one private project. You control who can see details of living people.
How working together worksNothing to install, nothing to lose with the laptop
Leaves runs in a browser, so there is nothing to install and no file to keep in step between two machines: the research is on our servers and opens on whichever one you are sitting at. The GEDCOM you already have comes in, and a full export goes back out whenever you ask for it.
How your tree gets in, and back outWhat it looks like when the evidence is kept
Two pieces of the application, drawn at the size they are used: a person with the confidence carried on each fact, and the tree canvas with a node that has no dates — which, in a real project, most of them do not.

More ways to follow the evidence
The tree is one view of the research. These tools work with the same people, families, places and sources, so each discovery stays connected.
- Explore the connections
- Move through the family tree, fan, sun, branches and network views. Compare lives with calendar, lifespan and Lexis views, and read events in a person’s timeline.
- Find the next question
- Review ancestor gaps and research coverage, run the tree checker, compare duplicate candidates and merge records. Consolidate places while keeping the evidence behind each decision.
- Keep the follow-up
- Create research tasks with linked records, an assignee, priority and due date. Filter your work by status, overdue items or the person and source you are investigating.
- Keep the original close
- Upload scans, photographs, PDFs, audio and video. Link them to the records they explain, record citation confidence and evidence inspection, and keep notes alongside your research.
- Put the research on paper
- Generate PDF ancestor and descendant charts, fan and hourglass charts, family group sheets, individual summaries, descendant narratives, Ahnentafel reports and family history books.
- Research together, privately
- Invite relatives to view your research in a private project. Living-person privacy controls let you decide which details collaborators can see.
Room for your family history. Free.
Build your tree, keep the evidence beside it, and follow the questions that matter to you. Start with one person or bring your existing GEDCOM.
Free gives you one project, up to 20,000 people, 250 MB for scans and photographs, and two viewer collaborators. It is not a trial and it does not expire.
The shoebox is not getting any better organised
The public beta is open. Create a free account, begin with one person or import your existing research, and tell us what could work better. No card needed, and your research is always yours to export.
Every name in a tree was once somebody's whole life.
