For the family historian

Decades of research,
still on paper.
Digital and understood, in an afternoon.

Bring in the binders, letters, and scans you have gathered for years. Heirsake reads them, lays out the people, places, and events, and shows you where each one came from.

Free instant sign-up, then 7 days to try it on your own pages. Bring one document or a whole box.

What are you trying to rescue?

A handwritten journal beside a tied bundle of old letters and a faded photograph, the kind of paper research a family historian keeps.

What survives the import

Bring it in as it is.
Keep what makes it yours.

  • Your layout and flow

    Chapters, sections, and the order you put them in come across as written, not flattened into a wall of text.

  • Photos with their captions

    The pictures in your pages come in as pictures, with the caption printed beside each one kept with it.

  • Handwriting, kept exactly as written

    A letter or inscription stays the image you scanned. We also read it into a hidden layer behind it, so it is searchable and the companion can cite it. We never retype it into the book.

  • A clickable outline, every word searchable

    Jump to any chapter, and find any line, name, or note across everything you brought in, handwriting included.

It shows its work

Impressive is easy.
Trustworthy is the point.

A tidy family tree you cannot check is a parlor trick. Heirsake earns the tidy version by proving every line of it.

Your family stays your family

The reading happens without
the AI ever knowing who.

Before anything reaches the AI, every identifying detail is swapped for a token. The model works the structure, the dates, and the relationships. It never sees who. The real names are restored afterward, so the work is done on your family without the model ever learning your family.

Your family’s details are yours. The reading is done on the structure of your family, never on who they are.

The understanding

It read your archive,
and it can prove every line.

Out of the pages comes a map of your family: the people, how they connect, the places they lived, the events they shared. Every connection carries the passage it was read from, so the tidy view is one you can check, not one you have to trust.

A finished, sourced chapter in the Heirsake reader, set in a warm serif with a copper drop cap.

The workspace

Finally untangle it,
and finish the book.

The half-finished project that grew too big to handle gets the tools it never had.

And it also gathers

The stories that were never
written down.

Some of the history is not on paper yet. Heirsake sends warm questions your family answers by phone, text, or voice, and weaves the answers into the same archive, in their own words and their own voice, kept alongside the documents you already have.

The book it becomes

The research was the hard part.

What comes out the other side is a keepsake the whole family reads, every line of it traceable to a source.

A Heirsake Memoir

The House on Linden Street

Seventy years, told over Sunday phone calls

In the words of Margaret Doyle

Chapter 1

A Kitchen That Was Always Warm

1948 - 1961

We never had much, but the kitchen on Linden Street was always warm. My mother kept the stove going from before dawn, and the whole house smelled of bread and coal smoke. I can still hear the screen door slap shut behind my brothers when they came in from the cold.

Christmas in the front room. I am the small one by the tree.

On Sundays my father would put on his only good shirt and we would walk to Mass together, all of us in a line by height. Afterward there was always someone at the table who hadn't been invited, and there was always enough. That was the rule of the house, though no one ever said it out loud.

I learned to read at that kitchen table, with my grandmother's finger moving under the words. She had come over from Galway with nothing but a tin box, and she told me once that the box was for the things you keep when you cannot keep anything else.

Chapter 2

The Dance at the Legion Hall

1962

I met your grandfather on a Friday in October, at a dance I almost didn't go to. He asked me twice and I said no twice, and the third time I said yes only because my friend Eileen pinched my arm.

He walked me home the long way so it would take longer, and he talked the entire time about a boat he was going to build and never did. I knew by the corner of Linden Street that I would marry him, though I made him wait a respectable while before I let on.

It stays yours

Your research, always
yours to take.

Bring in the family tree you already have, and take everything back out any time. Your people and relationships, your sources, and your stories export in open, documented formats, Markdown, HTML, and JSON, with your photographs, in a single download. No lock-in, no walled garden, no asking permission to leave.

Why now

Take the last word back.

The world is starting to tell our family stories for us, assembled from records, obituaries, and scattered posts by machines that never knew them. Heirsake is how a family keeps the true account: in their own voice, sourced, on their own terms, while they still can.

You have tried this before

Bring one page.

If it does not keep your handwriting and captions, make it searchable, and map your family in the time it takes to make coffee, close the tab. You have lost nothing but the coffee.

The history is already yours. This is where it finally lives.
