Frequently Asked Questions

Yes! You can build your family tree completely free without signing up. Create an account to save your tree permanently and access additional features like adding photos, writing time capsule letters, and sharing with family.
No account is required to use the family tree builder. Your tree is automatically saved in your browser, so it will still be there if you refresh the page. However, if you clear your browser data or use a different device, the tree will be lost. Create a free account to save your tree permanently and access it from any device.
You can add the four core relationships: parents, children, spouses/partners, and siblings. To add extended family like grandparents, aunts, uncles, or cousins, simply add the connecting people. For example, add your grandma as a parent of your mom or dad.
There's no limit! Add as many family members as you'd like to build out your complete family tree across multiple generations.
To share your family tree with others, you'll need to create a free KinPatch account. This allows you to invite family members who can then view and contribute to your shared family tree.
