atlas vs yantrikdb-server

atlas: Atlas is an open-source local-first cognitive memory system that implements AGM-compliant belief revision on a property graph. It adds a propagation engine called Ripple that recomputes downstream beliefs when an upstream fact changes. The system runs entirely on your laptop and includes a hash-chained ledger, continuous ingestion from multiple sources, and API surfaces for integration.; yantrikdb-server: YantrikDB is a cognitive memory engine designed for AI agents that goes beyond vector databases by implementing forgetting, consolidation, and contradiction detection. It provides token-efficient recall, proactive triggers, and a comprehensive API for memory operations, making it suitable for persistent AI systems.
