Echo Memory Wants AI Agents to Remember in Graphs

Field notes

Echo Memory models durable agent memory as a graph in which entities become nodes and facts become typed edges. The page shows a synthetic three-project capture and describes superseded facts remaining traceable through commands such as `echo-memory why <fact_id>`. Its stated storage layer combines PostgreSQL, pgvector, and Apache AGE, while extraction remains the calling agent’s responsibility rather than a server-side LLM step.
