Dev builds EchoVault, an app to train an AI version of yourself while alive
Emojinapp · reddit · 2026-10-25
A developer launched EchoVault, an app where you train an AI version of yourself (an "Echo") through regular question-driven check-ins while still alive. Instead of scraping your digital exhaust, it builds a model of your memories, values and reasoning, visualized as a 3D brain. You control what goes in and who gets access; interaction supports text, voice and video. The motivation: photos and chat logs can't explain how you'd think about something you never saw — loved ones could still ask "how would he have thought about this?"
