project-synapse-mcp vs root-kg
project-synapse-mcp: Project Synapse MCP server creates a persistent, compounding knowledge base by integrating a Neo4j graph database with an Obsidian Markdown wiki. It processes raw text into interconnected graph nodes with vector embeddings, while maintaining a human-readable wiki layer.; root-kg: ROOT is a local-first knowledge management system that connects your personal notes, meetings, and emails into a queryable intelligence layer. It builds an LLM-powered knowledge graph to provide cited, natural language answers to complex questions, outperforming traditional keyword search.
