Dev builds EchoVault, an AI replica trained via guided memory check-ins
Emojinapp · reddit · 2026-09-15
A developer demos EchoVault, an app that builds a personal AI replica not from a one-shot data dump but through guided check-ins about your memories, beliefs and personality. The demo shows the replica answering a question about the meaning of life and explores a 3D memory-network explorer (pending App Store review). Built mainly with Claude Code, Fable for planning, and Opus as workhorse/subagents.
