Best When

You need sophisticated long-term memory for OpenClaw agents with hybrid retrieval, reranking, and governance features.

Avoid When

You're not using OpenClaw, or you need a standalone memory/RAG solution.

Use Cases

  • • Persistent agent memory with semantic and keyword search
  • • Multi-scope memory isolation (global, agent, project, user)
  • • Self-improvement loops with structured learning extraction
  • • Memory export/import and bulk management via CLI

Not For

  • • Standalone vector database usage outside OpenClaw
  • • General-purpose document search
  • • Production use without an embedding provider API
