Penfield
Developer Tools
About
Penfield is a persistent memory plugin for OpenClaw agents, providing long-term recall, knowledge graphs, and cross-channel context. It uses hybrid search combining BM25, vector, and graph-based retrieval to surface relevant memories. Designed as a native plugin rather than an MCP server, Penfield achieves 4-5x faster performance while giving agents the ability to remember conversations, learn from interactions, and build structured knowledge over time.
