Obsidian LLM Hub

What it does

Obsidian LLM Hub transforms your Obsidian vault into an AI-powered knowledge base. It provides an interactive chat interface that can read, write, and edit your notes using function calling, and includes a visual workflow builder to automate complex multi-step tasks. It also features a local RAG (Retrieval-Augmented Generation) system for semantic search over your vault and PDFs.
