Description

Engram is an AI memory system designed to help agents remember past conversations, decisions, and knowledge automatically without losing context. It uses PostgreSQL with pgvector and pg_trgm extensions to provide hybrid keyword and vector search, along with a knowledge graph to connect decisions and consequences. The system features lifecycle hooks for automatic saving and compaction, proven in production with over 250,000 memories on a modest Mac mini M1 setup.
