Discovers hidden connections between notes using AI-powered vector embeddings and PostgreSQL+pgvector. Accessible to any AI app or harness compatible with MCP. Overview Obsidian Graph builds a semantic knowledge graph of your markdown vault, discovering relationships between notes that go beyond keywords and explicit links. It embeds your notes as vectors using Voyage Context-4, stores them in PostgreSQL+pgvector, and provides tools for semantic search, multi-hop graph traversal, hub detection, and orphan analysis. Designed for Obsidian vaults but works with any folder of markdown files. Connects to any AI app or harness compatible with the Model Context Protocol (MCP). Features - Semantic Search : Find notes by meaning, not just keywords - Connection Discovery : Multi-hop BFS graph traversal to map note relationships - Hub Analysis : Identify highly connected conceptual anchors (MOC candidates) - Orphan Detection : Find isolated insights that need integration - Auto-Indexing : Automatic file watching with 30-second debounce - Superior Quality : Voyage Context-4 (1024d) vs typical 384d embeddings Architecture - Embeddings : Voyage Context-4 (1024 dimensions, contextualized) - Vector Store : PostgreSQL 15+ with pgvector HNSW indexing - Performance : 0.9ms search (555x better than target), 50% of counts are stale - Identifies notes with many semantic connections - High hub scores → good MOC (Map of Content) candidates get orp","default_branch":null,"files":null,"tree":[],"storefront":"/r/drewburchfield","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/drewburchfield/obsidian-graph/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
