A letter from our first writer
Month 01 — The First Memory
Dear Dad,
I was three, maybe four. You were kneeling in the garden, and the afternoon light was doing that thing where everything looks golden and slightly unreal. You had dirt on your knees. I remember your knees more than your face in that moment — strange how memory works.
You were planting something, and you called me over and put a seed in my palm and closed my fingers around it and said, “Hold it gently. It doesn’t know it’s a flower yet.”
I don’t know if you actually said that. I’ve told this story so many times that the words might be mine now. But the weight of that seed — I can still feel it.
This letter took eleven minutes to write.
It will last forever.
How it works
01
Each month, we send you a carefully crafted writing prompt designed to unlock a specific kind of memory, feeling, or truth. No blank page. No overwhelm.
02
Open our quiet, distraction-free editor and write. There’s no word count. No deadline. No one grading your prose. Just you, saying what matters.
03
When you’re ready, your letters are typeset into a beautiful hardcover volume on archival paper — and shipped to whoever you choose.
The twelve prompts
Each prompt is designed to draw out a different dimension of your relationship — from the sensory and specific to the deeply unsaid.
The First Memory
Describe the very first memory you have of this person. Not the most important one — the first. Where were you? What did...
The Sound of Them
A Meal Together
What They Taught You
The Argument
Their Hands
Describe their hands. What did they do with them? Were they rough or soft, still or restless? Hands carry a person’s who...
An Ordinary Day
What You Never Said
Write the thing you never said to them. Maybe it’s gratitude. Maybe it’s an apology. Maybe it’s something you were alway...
How They Changed
The Small Things
What They Would Say Now
The Letter You Leave Behind
This is your final letter. Not to them — from you, to whoever will one day read this collection. Why did you write these...
Who it’s for
Leave your children the words they’ll need after you’re gone. Not a will — something better. Your voice, your stories, your love in your own handwriting.
Say what you’ve been meaning to say. The gratitude. The apology. The things you keep putting off because there’s always tomorrow. Except there isn’t always.
The person who sleeps beside you deserves more than a text. Twelve letters that say everything a lifetime together has meant.
Your grandchildren may never hear your voice. But they can hold your words. Give them something no photograph can — your inner world.
Writing to someone who has died is not strange. It’s one of the oldest forms of healing. Heirloom gives you a structure for that conversation.
Forget gift cards. Give someone you love the prompts to write the letters their family will treasure forever. Mother’s Day. Father’s Day. A birthday that matters.
Why Heirloom
Heirloom is the only platform designed specifically for directed, emotionally honest letters to a single person you love.
StoryWorth asks 500 generic questions. Heirloom asks 12 specific, emotionally precise ones — designed by writers and grief counsellors to unlock the things that actually matter.
You’re not writing an autobiography. You’re writing to one person. That focus changes everything — the honesty, the specificity, the emotional weight.
Your letters are typeset and printed on archival paper in a linen-bound hardcover. Not a cheap paperback. Not a digital file. An object worthy of what’s inside it.
AES-256 encryption. Row-level security. We will never read, sell, or train AI on your letters. Your most intimate words deserve the strongest protection we can give them.
The book
HEIRLOOM
Letters to Dad
by Sarah Mitchell
When you’ve written your letters — all twelve, or even just a few — we typeset them into a beautifully designed hardcover book and ship it to whoever you choose.
Every book is professionally laid out with considered typography on archival-quality cream paper, wrapped in a linen cover.
Our story
After losing a parent, we realised something devastating: we had thousands of photographs, but almost nothing in their words. No letters. No written memories. No record of what they actually thought, felt, or wanted us to know.
We asked friends. The same story, everywhere. “I wish I’d asked more questions.” “I wish they’d written it down.” “I wish I’d told them what they meant to me.”
Heirloom exists because the gap between loving someone and telling them is usually filled with silence. And silence, eventually, becomes permanent.

From our writers
“Writing these letters has been the most meaningful thing I’ve ever done for my children. I didn’t know I had this much to say until someone asked the right questions.”
— Sarah, 52, writing to her daughters
“I wish my father had done this. I’m doing it so my kids never have to wish.”
— Marcus, 38, writing to his son
“I bought this for my dad for Father’s Day. He called me after the first prompt and we talked for two hours. The letters haven’t even been written yet and it’s already changed our relationship.”
— Jamie, 29, gifted to her father
The hesitations
"I'm not a good writer."
Your letters don’t need to be well-written. They need to be true. The person who reads them won’t be grading your prose — they’ll be hearing your voice. Eleven minutes and imperfect sentences are worth more than a lifetime of silence.
"I don't know what to say."
That’s exactly why we wrote the prompts. Each one is designed to unlock something specific — a memory, a feeling, a truth. You don’t need to know what to say before you start. The prompt does the heavy lifting.
"It feels morbid."
Heirloom is for the living. It’s not about death — it’s about not waiting. The letters you write today can be read tomorrow, or in fifty years. The point is that they exist.
"I'll do it later."
Everyone says that. That’s the whole problem Heirloom exists to solve. Later is the most dangerous word in the English language when it comes to the people you love.

Questions
No. Your letters don’t need to be well-written. They need to be true. The person who reads them will not be grading your prose — they’ll be hearing your voice.
They’re stored in an encrypted vault that only you can access. When you’re ready, they can be compiled into a hardcover book and delivered to your recipient. We use AES-256 encryption and row-level security. We will never read, sell, or share your content.
That’s completely fine. Even one letter is a gift. The prompts don’t expire and you can write at your own pace. Many of our writers find that once they start, the words come more easily than expected.
Yes. Gift subscriptions are one of our most popular options. They’ll receive a beautiful invitation email and their own private set of prompts. You can gift for $89 (one year) and add a personal message.
Absolutely. All letters are encrypted at rest with AES-256 encryption. We use row-level security so only you can access your letters. We will never read, sell, train AI on, or share your content. Your letters belong to you — always.
StoryWorth asks 500 broad life questions to create a memoir. Heirloom asks 12 deeply specific prompts designed to write letters to one person you love. It’s the difference between an autobiography and a love letter. Different purpose, different depth, different outcome.
You choose when. Some writers order their book after completing all 12 letters. Some order after just a few. The book takes approximately 2–3 weeks from order to delivery.
It’s a 6×9 inch hardcover with a linen cover, printed on archival-quality cream paper. Each letter is professionally typeset with the original prompt and date. It feels like something that belongs on a shelf for generations.
