Agent Brain – 7-layer cognitive memory for AI agents (open source)

Agent Brain introduces a revolutionary 7-layer cognitive architecture that gives AI agents persistent memory, reasoning, and prediction capabilities without requiring expensive LLM calls for memory operations. Unlike traditional stateless agents that forget everything between sessions, this open-source system runs locally using PostgreSQL and enables agents to remember past interactions, learn from decisions, anticipate future needs, and even "dream" to consolidate memories overnight, proven in production at Swiss property management company Valtis.
