EchoMind is a voice-first AI personal memory agent designed to help people remember the context behind everyday conversations. Instead of manually writing notes, users can speak naturally about people, tasks, plans, events, and important details. EchoMind uses AssemblyAI’s realtime Voice Agent technology for live voice interaction, then passes the conversation into an AI layer that extracts structured information and relationships. Those memories are stored in Neon PostgreSQL and represented as a Personal Memory Graph. Users can retrieve memories, search connected context, complete tasks, and forget information. EchoMind also resolves relative time such as “tomorrow” or “in 2 hours” into absolute dates so relevant memories can be considered for proactive suggestions. The result is a voice-first memory system that listens, understands, remembers, connects, and brings context back when it becomes useful.
