Everythingyou'velived.Preservedforeveryonewhocomesafter.
A permanent archive of your life. Every memory structured, emotionally understood, and cryptographically anchored — built to outlast any platform, including ours.
Your life has a structure.
Most people never see it.
Every moment you capture becomes part of an evolving pattern. Seyr finds the connections you missed.
The call that changed everything.
You almost didn't answer.
Someone you never want to forget.
The way they laughed. The way they looked at you.
The day you finally understood.
Three years of confusion resolved in one afternoon.
A place you'll always return to.
Not on a map. In a feeling.
The moment grief became gratitude.
You didn't see it coming. Neither did we.
March 2019. October 2022. Both times you were alone. Both times you made the biggest decision of your life within 72 hours. Seyr noticed. You didn't.
You've felt this exact feeling twice. June 2019 and November 2022. Your voice slowed down the same way both times. Same pause before the same word. Seyr matched them.
The memory you captured on August 14th is fading faster than your others. You haven't returned to it in 4 months. Seyr is holding it. But you should visit soon.
Every 18 months you go quiet. Fewer captures. Shorter entries. Then something breaks open. You're at month 16. Seyr is watching.
The moment you recorded on the night of April 3rd — the one you almost deleted — has been permanently sealed. It exists now regardless of what you decide about it.
You've mentioned her in 14 separate moments across 3 years. Never as the subject. Always in the background. Seyr noticed she might matter more than you've admitted.
You've been to that location 6 times. You only captured it once. But your heart rate spiked the same way each visit. Something happens to you there.
Archives export in the Memory Preservation Protocol (MPP) — an open, self-describing format with cryptographic integrity proofs. Readable by any compliant system, including institutions, without Seyr. Spec →
Preserve them now. While there's still time to do it right.
This is not a grief product. It's the opposite — proactive preservation of the people who shaped you, captured with intention while you still can. Their voice, perspective, and presence become permanent nodes in your graph. Not a chatbot. Not a simulation. A real archive of a real person, held with cryptographic permanence.
The people who shaped you — preserved with the fidelity they deserve.
Invite the people who matter most to record voice, messages, and memories directly into your archive. Their contributions become permanent nodes in your life graph — anchored, signed, and held forever.
Seyr resurfaces them when the emotional context calls for it — not as a notification, but as a dimension of your own living record.
Your story, from every angle that lived it.
Every life is bigger than one person's memory of it. Seyr Circle lets the people close to you add their perspective — their photos, voice, and moments — woven directly into your graph as contributing nodes.
Seyr maps the relationships and emotional threads between their moments and yours — building a record of your life that no single person could have assembled alone.
Every contribution from your Circle is cryptographically signed to that person and anchored to your graph — so the record of who gave it, when, and in what emotional context is permanent. This is not a scrapbook. It is structured provenance for a human life.
Join the waitlist to get early accessYour memories belong to you.
Even if Seyr disappears.
Every archive exports in the Memory Preservation Protocol — an open, self-describing format readable by any compliant system. Your memories are encrypted at rest with AES-256, keys managed through hardware security modules. Nothing is captured without your intent. Nothing is shared without your permission.
Current architecture: encrypted at rest via AWS KMS. Full client-side key management coming in a future release. We will never claim stronger guarantees than we've built.

Questions about Seyr.
What is Seyr?+
Seyr is a personal memory operating system — not a journal, not a photo app, not a memoir service. It builds a living graph of your life: every person, place, moment, and emotion connected and understood. Your archive is cryptographically permanent and exports in an open format readable by any institution, indefinitely.
How is Seyr different from StoryWorth or Remento?+
Those services turn memories into books. A book is a document — flat, static, finished. Seyr builds a graph that grows with you: it understands who appears across your memories, detects patterns across decades, and surfaces the right moment at the right time. The intelligence is the product.
How is Seyr different from Google Photos or iCloud?+
Google Photos stores files and runs face detection. Seyr builds structure. It knows that the person in your 2003 photo and your 2024 photo are connected to the same chapter of your life — and why that matters. Your Seyr archive is also portable and cryptographically permanent. Google can delete your account. Seyr cannot erase a Bitcoin-anchored timestamp.
What is the Memory Preservation Protocol?+
MPP is the open archive format Seyr exports your data in. It's a typed property graph specification — not a proprietary database dump, not a PDF. Every memory node carries a cryptographic fingerprint, anchored simultaneously across multiple independent blockchains. Any compliant reader — including universities, libraries, or future platforms — can verify and read your archive without Seyr's involvement.
What happens to my memories if Seyr shuts down?+
Nothing. Your archive is in your hands as an MPP export — a self-describing, open format with embedded multi-chain integrity proofs. It doesn't require Seyr's servers to read or verify. This is a deliberate architectural commitment, not a marketing claim.
What is Seyr Legacy?+
Legacy is not a grief product. It's proactive preservation — capturing the voice, perspective, and emotional presence of the people who shaped you while you still can. The people you preserve in Seyr Legacy are held in the same permanent, structured graph as your own memories. Seyr surfaces them in relevant moments, not as a chatbot, but as a dimension of your own archive.
What is Seyr Circle?+
Your life is not just your memories of it. Seyr Circle lets the people close to you contribute their perspective — their photos, their voice, their angle on shared moments — woven into your permanent record. One life, understood from every angle.
Who owns my memories?+
You do. Memories are encrypted at rest with AES-256, keys managed via hardware security modules. Your archive exports in an open format you control. We don't store plain text. We don't train models on your data. And we'll tell you exactly what protections are in place — we will never overstate our security guarantees.
