Sakdulur is a private family tree you build together with your family.

"Sak dulur" is Javanese for "one family". Map parents, partners and children across generations, add photos and stories, and invite relatives to fill in their own branches. It works for a small household as well as a whole trah or bani with hundreds of members.

A real family tree

• Couples side by side, children below their own parents, ancestors and descendants together
• Remarriages, divorces and engagements, each child under the right couple
• Birth, adoptive, step, foster, guardian and milk parents, with foster and step links drawn dashed
• Dates (even "about 1920"), places, photos and notes

Build it together

• Invite relatives as editors or viewers with a link
• Share a branch with the people who know it best
• Copy a branch between your tree, your spouse's and your in-laws'

Ask and update by chatting

• "Who is Ayu's father?" or "Add Rani as Ayu's daughter, born 1994."
• Nothing is saved until you press Apply; answers are generated by AI and can be reported

Private by default

• Every tree is private: only the people you invite can see it
• No ads, and your data is never sold
• Export as a picture, Excel or GEDCOM, or delete your account anytime
