Penfield - Persistent Memory and Knowledge Graphs for AI Agents
Penfield gives AI agents long-term memory that compounds over time. Instead of starting every session from zero, your agent remembers conversations, learns preferences, connects ideas, and picks up exactly where it left off.
Core capabilities:
- 16 tools covering memory CRUD, knowledge graph, context management, artifacts, and reflection
- Hybrid search with tunable weights — BM25 (keyword), vector (semantic), and graph traversal
- Knowledge graph with 24 relationship types across 8 categories (evolution, evidence, hierarchy, causation, implementation, conversation, sequence, dependencies)
- Context checkpoints for session handoff between agents or channels
- Artifact storage for files, diagrams, and reference docs
- 11 memory types intelligent filtering
- Personality system with configurable personas via the portal
Also available as a Claude Connector, Claude Code integration, native OpenClaw plugin (4-5x faster), and direct API.
