ContextGraph vs memex

ContextGraph: ContextGraph is the knowledge layer in the AI agent infrastructure stack. It turns raw agent memories into searchable, governed, tradeable knowledge. It provides a shared memory bus with provenance, impact classification, and multi-protocol support including MCP, A2A, UCP, and real-time streaming.; memex: memex provides persistent memory for AI coding agents using atomic knowledge cards with bidirectional links. It stores insights from each session and recalls relevant cards before starting new tasks, enabling agents to build on previous knowledge. No vector database or embeddings needed—just markdown files.
