An open-source Obsidian plugin that adds a privacy-focused AI assistant to your note vault. It embeds your notes and uses a RAG pipeline with local LLMs (via Ollama) or ChatGPT to answer questions with reference links back to source notes, and can run completely offline.

Use cases

• chat with my obsidian notes using a local llm
• ask questions about my notes and get citations
• run a private ai assistant offline over my vault
• set up a rag pipeline for my second brain
• use ollama with obsidian
• query my knowledge base with an llm without sending data to the cloud

When to choose

• you use Obsidian and want an AI assistant grounded in your own notes
• privacy matters and you want fully offline operation with Ollama
• you want answers with traceable reference links to source notes

When to avoid

• you don't use Obsidian or another note app
• you need a standalone chatbot outside a note-taking workflow
• your vault is unstructured, which degrades retrieval quality
