Overview
semantic-memory is a local-first knowledge graph for AI agents. It's the memory system that powers the AiDENs autonomous loop, but it works standalone as an MCP server with any compatible client (Claude Desktop, Cursor, Hermes).
Unlike Zep, MemGPT, or ChatGPT memory, it has provenance on every fact, bitemporal search (it knows what it believed on any date), typed graph edges, contradiction detection, factor graph belief propagation, and RL-trained adaptive retrieval routing.
What's on the demo page
The demo page covers:
- Feature comparison table (10 features vs Zep, MemGPT, Mem0, ChatGPT Memory)
- How it works: the library + the MCP server (48 tools, 15 HTTP endpoints)
- Install and configure: step-by-step for Claude Desktop and Cursor
- Tool profiles: lean (34 tools) / standard (45) / full (48)
- What happens when you close the loop: AiDENs metrics (14 iterations, 12/12 completed, 29 facts captured)
- Real captured facts from the autonomous namespace
