Building a Second Brain with Obsidian and Claude Code
Obsidian and Claude Code are two tools that can be used together to create a personalized knowledge base. This combination allows users to store notes, goals, and data in one place and have Claude Code access this information to provide more accurate responses. ## Overview Obsidian is a free tool that allows users to create a knowledge base using Markdown files. It can be used to store notes, goals, and data, and provides features such as linking between notes and tagging. Claude Code, on the other hand, is a coding assistant that can be used to automate tasks and provide answers to questions. By combining the two, users can create a system that helps with decision-making and provides more accurate responses. ## Setting Up the System To set up the system, users need to follow these steps: 1. Install Obsidian by downloading it from the official website and creating a new vault. 2. Install Claude Code using npm by running the command `npm install -g anthropic-ai/claude-code`. This requires Node.js to be installed. 3. Connect Claude Code to Obsidian by opening a terminal in the vault folder and running the command `claude`. Alternatively, users can install the Obsidian Claude Code plugin and enable it in the settings. 4. Load knowledge into the system by adding notes, goals, and data to Obsidian. It is recommended to use descriptive file names, such as `meeting-investor-january.md`, to make it easier for Claude Code to find the relevant information. ## What it Does The combination of Obsidian and Claude Code provides several benefits, including: * Claude Code can access the user's knowledge base and provide more accurate responses. * The system can help find connections between projects and provide answers based on the user's own knowledge base. * Users can store notes, goals, and data in one place and have Claude Code help with decision-making. The system has been used by Andrey Karpathy, co-founder of OpenAI, who switched to using this setup for his coding needs. With over 325,000 views in two days, this setup has gained significant attention. Obsidian is free, while Claude Code is part of the Pro subscription, which costs around $20 per month. In conclusion, the combination of Obsidian and Claude Code provides a powerful tool for creating a personalized knowledge base. By following the steps outlined above, users can set up a system that helps with decision-making and provides more accurate responses.
