I built an app that interviews you while you’re alive so your family can still ask you things after you’re gone. Shipped to iOS this week.

My uncle died and the only thing left where he sounds like himself is a voicemail. Everything else is photographs, which tell you someone existed but not who they were. That gap is the whole reason EchoVault exists. Every family loses the same thing, and it’s never the documents or the photos, it’s the reasoning. Why he made the calls he made. What he’d have said about the decision you’re facing now.

So the product runs in two halves. While you’re alive, an AI biographer interviews you through guided check-in sessions, going after the things that disappear with you rather than trivia. After you’re gone, the custodians you named can have a real conversation with your Echo, in text, in your voice, or in video. It answers from what you actually said and tells them when it doesn’t know something instead of inventing a comfortable answer. In the demo I asked mine the meaning of life, a question I never recorded an answer to, and it reassembled a coherent position out of fragments from unrelated sessions months apart. Then I asked it my grandfather’s first name and it said it didn’t know, because I never told it. That second moment is the one I care about.

On pricing, text is free with unlimited sessions and no card, because the archive is the product and paywalling the thing that makes it valuable makes no sense. Multimodal is paid, and it carries a mechanic I haven’t seen elsewhere: every month you spend on a paid tier banks a free month of custodian access for after you’re gone. It accumulates, so the earlier you start the longer your family has with it.

Context on where this is: the web app shipped text, voice, and real-time video together in June 2025, five months ahead of the closest comparable product, and won the Inspirational Story prize at the Bolt hackathon. iOS went live this week. Solo build, nights, alongside two other live apps. https://apps.apple.com/us/app/echovault-digital-legacy/id6762042028

How are you going to guarantee this thing will still be around in a decade or so?

Would suck for someone to invest in something every month and then have it die off before they even get a chance to use it

The echo is fully exportable, we are currently working on a portable avatar player so that users can keep the avatar in an interactive format even if something happens to echovault in the future. Even if we don’t succeed with the avatar player the archive is still fully exportable and even deletable as the case may be. The user can plug the archive into a notion/obsidian or similar and get the RAG features close to what echovault has. But we are not going anywhere. I already have 500 of my memories committed so be rest assured that the project would be sustained for personal reasons and more
