Family Tree Builder

Visual genealogy • interactive

Turn family stories into clear, beautiful family trees.

Quickly map relationships, fix mistakes, and share an organized family history. Interactive editing, smart arrangement, and clean visual exports make research and storytelling effortless.

  • Auto-layout — Clean hierarchical layouts (see familyTreeLayout)
  • Interactive editing — Add people, spouses, collapse branches
  • Export & share — Static JSON / images for catalogs
  • Accessible UI — Keyboard & screen reader friendly

Why mapping family history is painful

Manual charts get messy fast. When families have multiple marriages, adoptions, or missing records, diagrams become hard to read and even harder to correct. That slows research and breaks storytelling.

Where other tools fall short

  • Static exports that need manual cleanup
  • Limited controls for complex relationships
  • Large trees that overwhelm readers

How this helps you

Edit directly on the chart, let the layout organize the family, and collapse branches to focus on the story you care about. It’s faster to correct errors, easier to explain relationships, and simple to share polished visuals.

No steep learning curve — built for people who want clear results, not extra steps.

Real features that save time

Every feature is designed to help you understand and share family stories faster — less fiddling, more clarity.

Auto‑Arrange

Automatically organize family nodes into a clean, readable layout so you can focus on relationships instead of positioning.

Smart marriage handling

Keep spouses visually together and ensure parentage stays accurate—even for complex, multiple-marriage families.

Focus with Collapse

Hide distant branches to highlight the people and stories you care about, then expand when you’re ready.

Direct visual editing

Click and edit on the chart: add people, adjust relationships, or drag nodes for instant updates—no menus, no guesswork.

Share & export

Export clean JSON or polished images to share with relatives, publish in reports, or archive your research.

Fast, private interaction

Most work happens in your browser for quick, responsive edits. Keep data local until you decide to share.

How it works — 3 simple steps

1. Start with your data

Import a file or begin from the sample to see your family instantly.

2. Let the editor organize it

The layout arranges people into a clear chart while keeping relationships correct.

3. Edit and share your story

Make corrections, collapse branches, and export a clean image or data file to share with family.
