OpenMemory is a local-first long-term memory engine designed specifically for AI systems, using SQLite for local storage to enable persistent memory without cloud services. It overcomes the complex setup, cloud dependency, and vendor lock-in issues of traditional vector databases, providing multi-dimensional memory structures including semantic, episodic, procedural, emotional, and reflective memory through its Hierarchical Semantic Graph architecture (HSG v3). The system supports time-aware fact tracking, capable of handling information that changes over time, and provides interpretable recall paths. OpenMemory integrates easily, requiring only 3 lines of code to add memory to AI systems, with performance tests showing response times of 115ms and throughput reaching 338 QPS. The project supports multiple deployment methods including Node.js, Python SDK, and backend servers, and provides VS Code extensions and MCP protocol integration, enabling AI assistants to access developers’ coding history and project context.
