post-cortex vs synaptic-memory
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.; synaptic-memory: Synaptic Memory is a knowledge graph and MCP tool server for LLM agents. It automatically ingests data from various formats into a structured graph, then provides 29 atomic tools for agents to explore. No LLM cost at indexing time.
