Building the AI Memory Stack: Layered Storage, Async Extraction and Atomic Persistence

Every AI agent you build today can hold a conversation. It can reason, use tools, and chain together complex workflows. But the moment a session ends, everything disappears. The agent forgets who you are, what you were working on, and every preference it learned during the conversation. This is not a minor inconvenience. It is the single biggest gap between agents and production agents. A customer agent that forgets your previous tickets. A coding assistant that re-asks your framework preferences every session.
