Discover a game-changing method to create and manage your own private knowledge base using Obsidian, eliminating the need for complex Retrieval Augmented Generation (RAG) applications or fine-tuning AI models.

In this post, we explore how to integrate your personalized data, including Odoo apps and custom projects, into a dynamic vault system that seamlessly connects with AI agents for instant, context-aware answers. This approach is perfect for professionals across all fields—whether you're in technology, healthcare, manufacturing, or trading—to efficiently organize and reuse your knowledge anywhere.

Getting Started with Obsidian

To build your private knowledge base, start by installing Obsidian and setting up your vault. Follow these steps:

  • Download Obsidian from Obsidian MD.
  • Create a new vault to store your knowledge base.
  • Set up a raw data folder for your sources and data collection.

Implementing Karpathy's LLM Wiki Prompt

Next, to leverage AI capabilities, implement the LLM Wiki prompt developed by AI expert Andrej Karpathy. This prompt will guide your AI agent to function as your second brain, providing quick access to your stored knowledge. Here’s how to do it:

"You are now my LLM Wiki agent. Implement this exact idea file as my complete second brain. Guide me step-by-step."
Andrej Karpathy

With this prompt, you’ll create the CLAUDE.md schema file with full rules, set up index.md and log.md, define folder conventions, and show the first ingest example. This structure ensures all interactions follow a consistent schema, making knowledge retrieval efficient.

Connecting AI Agents for Instant Answers

Once your vault is set up and the prompt is implemented, the next step is to connect your AI agents for instant answers. This is how you can achieve that:

  • Integrate AI tools that can interact with your Obsidian data.
  • Test the AI's responses by asking questions related to your data.
  • Refine your approach based on the AI's performance and adjust the schema as needed.

Use Cases for Your Private Knowledge Base

Your private knowledge base can serve numerous purposes:

  • Managing Odoo apps and related documentation.
  • Storing YouTube content transcripts for easy reference.
  • Organizing personal data, projects, and insights.

This method not only simplifies your knowledge management but also enhances your productivity by making information retrieval quick and straightforward.
