Obsidian Second Brain

Overview

Turning an Obsidian vault into an interactive, searchable knowledge base accessible through the web. Uses RAG (Retrieval-Augmented Generation) to let you chat with your notes using any LLM provider.

How It Works

1. Obsidian vault synced to a GitHub repository
2. Notes are chunked and embedded into a vector store
3. Semantic search finds relevant notes for any query
4. LLM generates answers grounded in your actual notes

Goals

• Browse vault notes directly on the website
• Chat with your knowledge base using Claude, GPT, or local models
• Toggle between LLM providers seamlessly
• Keep everything private behind authentication
