Hello, Kinstripe — building the family tree tool we always wanted

Most family tree software was built for a world that no longer exists. It assumed one nuclear family, one tidy lineage, and one person in charge of the record. You'd enter your data, get a static chart you could print, and that was it. No sharing. No collaboration. No updates when your cousin corrected a birth year or your aunt uploaded a photo she'd been keeping in a shoebox for forty years.

We built Kinstripe because that model needed to change.

The first problem was real-time collaboration. If you've ever tried to build a family tree with other family members, you know the frustration: emailed spreadsheets, conflicting versions, someone accidentally overwriting work, and months of effort fragmented across three different apps. Kinstripe works the way a Google Doc works — multiple family members editing at the same time, seeing each other's changes as they happen, with a history you can roll back if something goes wrong.

The second problem was harder: real families aren't trees. They're networks. Step-parents, half-siblings, adopted children, blended households, people who have meaningful family relationships that don't fit neatly into a biological chart. Every tool we tried forced us to either distort the real picture or leave people out entirely. That felt wrong.

So we built Bridged Trees. The idea is simple: each family branch lives in its own tree, owned and managed by the people who belong to it. When families connect — through marriage, adoption, a blended household, or any relationship that matters — the tree owners can create a Bridge. A Bridge lets both trees show the connection without merging the data or handing over control. A step-parent appears in the child's tree. An adoptee can see both their adoptive and birth families, if both sides agree to connect. Half-siblings can see each other without either family losing their own private record.

Privacy is built into this from the start. You decide what your tree shares, who can see it, and whether to accept a Bridge request at all. Nothing is exposed without permission.

We're in early access now, and we're looking for families who want to help shape what Kinstripe becomes. If your family has a complicated history — and whose doesn't — we'd love to have you.
