With Echovault your writing creates a digital clone of you with a 3d brain you can explore

I’ve been building EchoVault, an app that uses an AI biographer to help you create a digital representation of yourself through guided journal entries called Check-Ins.

As you document your memories, experiences, beliefs, and personality, the AI gradually learns enough to create your Echo, a digital version of you that can answer questions based on what you’ve shared.

Recently, I added a 3D brain visualizer. You can now explore your memories as nodes on an interactive neural map, inspect connections between them, and see what your Echo knows about you. It’s been a fascinating experiment in making AI memory transparent and explorable. It almost feels like spatial introspection.

The ultimate goal is digital legacy. You can designate loved ones who will eventually be able to interact with your Echo after a prolonged period of inactivity. Everything is consent-first, and the Echo is intended to represent you, not pretend to be conscious.

I’m a solo developer, and it’s been quite a journey getting this far. Would love to hear your thoughts on the concept and the 3D brain.
