post-cortex vs samyama-graph
post-cortex: Post-Cortex is an MCP server that provides AI assistants with persistent memory. It stores conversations, decisions, and insights in a searchable knowledge base with automatic entity extraction. All processing runs locally with no external API calls, ensuring privacy.; samyama-graph: Samyama is a graph-vector database written in Rust. It supports OpenCypher queries, Redis protocol, vector search, and graph algorithms. It can handle billions of edges on a single machine.
