Family tree, reimagined

Every name.
Every branch.
Every story.

Rootline maps your whole family and tells you exactly how anyone is related to you — in plain language, instantly.

The problem

"Wait — whose kid
is that again?"

Family reunions are wonderful and overwhelming. Forty cousins, in-laws of in-laws, names you've heard once. Hover any name below — Rootline already knows.

What Rootline does

Built around the connections that matter

Relationship engine

Our graph algorithm finds the shortest path between any two people and generates a natural-language label — "Your first cousin once removed" — automatically, every time.

Claim your profile

Family members get an invite link to claim their own node, add photos, and keep their own info current. Everyone owns their own branch.

Birthday reminders

Never forget a birthday again. Rootline surfaces upcoming birthdays across the whole tree and tells you who they are and how they're related to you.

Live sync

Realtime updates keep every family member's app in sync. When someone adds a new branch, everyone sees it the moment it's saved.

Visual tree

A clean, scrollable family tree makes the whole picture visible at once. Tap any node to see the full profile and their connection to you.

Private by default

Row-level security on every table. Your family data stays yours — no scraping, no profiling, no surprises.

How it works

Four steps to your
complete family picture

01

Start your tree

Add yourself and the family members you know. Names, birthdays, relationships — as little or as much as you have to begin.

02

Invite family members

Send invite links so relatives can claim their own profiles, fill in their branches, and grow the tree from every direction.

03

Explore the connections

Open anyone's profile and see instantly — "Your second cousin", "Your great-aunt" — in plain language, always accurate.

04

Never forget again

Birthday reminders, relationship context at every reunion, a living record that grows with your family for generations.
