Engram: A Local-First Persistent Memory Architecture for Conversational AI Agents
Abstract
Engram is a local-first persistent memory system for AI agents combining multi-strategy retrieval (semantic embeddings, BM25, temporal decay via Reciprocal Rank Fusion), a three-tier memory lifecycle with LLM-based consolidation, a sparse entity-relationship graph, and a belief-revision model. Runs on consumer hardware with no cloud dependency. Ships TypeScript and Python SDKs and an MCP server for Claude Desktop/Cursor integration.
