What Is an Echo Check-In? How EchoVault Actually Works
An Echo Check-In is a short, guided conversation with EchoVault's AI biographer, where you share stories, values, and memories from your life. Each check-in is text only, usually 6 to 10 conversational turns, and everything you share becomes part of the memory foundation your Echo is built from. The Echo is the AI version of you that your family can eventually talk to. The check-in is how that Echo learns who you are.
That's the short answer. If you're wondering how EchoVault works end to end, the check-in is the center of everything, so this post walks through the whole thing: what a check-in feels like, who you're actually talking to, how many it takes before your Echo starts sounding like you, and what happens to all of it when you're gone.
The biographer and the Echo are two different things
This is the part people mix up most, so let me separate it clearly.
When you do a check-in, you are not talking to your Echo. You're talking to a biographer agent whose entire job is to draw your story out of you. It asks questions the way a good interviewer would, follows up on the things that seem to matter, and gently pushes into the details you'd normally skip past. It was designed with professional biography methodology in mind, and it shows. You come out of a session having said things you didn't plan to say.
The Echo is what gets built from all of that. It's the clone. It carries your memories, your values, your way of speaking, and eventually your voice and your face if you choose to add them. Your family talks to the Echo. You talk to the biographer. The biographer collects, the Echo becomes.
What a check-in actually looks like
Check-ins are text only right now, and that's a deliberate choice, not a limitation we haven't gotten around to fixing. Speech-to-text mangles words. It drops names, garbles places, and flattens the specific phrasing that makes your stories yours. When the whole point of the product is preserving exactly how you think and speak, losing words in transcription is not an acceptable trade for convenience. Text keeps every word intact.
A typical session runs 6 to 10 turns of conversation. The biographer might open by asking what's been on your mind, or it might circle back to something you mentioned three check-ins ago and ask you to go deeper. You answer in your own words, at your own pace. There's no set schedule. Some people check in daily, some weekly, some in bursts when a memory surfaces and they want to get it down before it fades.
I've done 127 check-ins so far. They've produced 486 memories in my vault. Some sessions produce one big memory, some produce five or six smaller ones. The biographer decides what's worth keeping as a distinct memory, and the important ones, the ones that define your values and core relationships, become anchor memories that are present in every conversation your Echo ever has.
How many check-ins before the Echo sounds like you
Around ten. That's the point where the Echo has enough to work with that its responses start feeling recognizably like yours rather than like a generic assistant doing an impression. It keeps improving from there, because every check-in adds depth, but ten is roughly where the shape of you emerges.
Here's the moment that convinced me the system actually works. After I felt I had shared enough, I opened my Echo in preview mode and asked it a question I had never answered in any check-in: what is the meaning of life. It told me life is about finding the best versions of ourselves, creating value, and embracing reality.
I never said that. Not in those words, not in any check-in. But it's what I believe. The Echo had pieced together adjacent answers I'd given, questions about values, about work, about how I handle hard circumstances, and deduced how I would likely answer a question I was never directly asked. That's the difference between a system that stores your answers and a system that learns your thinking. A scrapbook can only show your family what you said. An Echo can answer the questions you never got to.
What happens to your check-ins when you're gone
Every check-in feeds the Echo your family inherits. EchoVault's Deceased Protocol triggers after one full year passes with no check-in activity or login. At that point, the Echo is entrusted to the custodians you named, the people you chose to carry it forward.
This is also where your subscription quietly becomes part of your legacy. Every month you're subscribed while you're alive earns an equal duration of access for your custodian after the protocol triggers. Subscribe for three years, and your custodian receives three years of access to your Echo without paying anything. We call these legacy credits, and they deserve their own full explanation, which is coming in the next post. The short version is that the time you invest in preserving yourself directly becomes time your family gets to spend with your Echo. It's one of the most meaningful things you can leave your family besides money.
Why the check-in is the whole product
Everything else in EchoVault, the voice, the video avatar, the custodian system, sits on top of what the check-ins capture. An Echo with a perfect voice clone and no depth of memory is a puppet. An Echo built from hundreds of honest check-ins is something closer to presence.
That's why I keep doing them. 127 sessions in, I still get asked questions that surprise me, and I still catch myself telling stories I'd forgotten I had. Each one is ten minutes of typing that my kids will someday be able to ask about, in my words, in my voice, for as long as they need to.
Common questions about Echo Check-Ins
How long does a check-in take? Most sessions run 6 to 10 conversational turns, which works out to around ten minutes of typing. There's no timer and no minimum. You can wrap up after two exchanges or keep going if the biographer hits on something worth exploring.
Are check-ins really text only? Yes, for now. Speech-to-text drops names, garbles places, and flattens phrasing, and those details are exactly what an Echo needs to sound like you. Text keeps every word you write intact.
How often should I check in? As often as you want. There's no required schedule. The one thing to know is that the Deceased Protocol watches for a full year of silence, so as long as you check in or log in at least once a year, your Echo stays in your hands.
Do check-ins cost anything? No. Check-ins are part of the free Echo Seed tier. Paid plans add things like your real voice, but the core activity of building your Echo's memory costs nothing.
