Nick Spisak outlines a straightforward method for creating a personal knowledge base using AI, based on a folder structure rather than complex software. The system requires just three folders: one for raw source material, another for the AI-generated wiki, and a final one for outputs. Users can fill the raw folder with various materials—articles, notes, and images—without needing to organize or clean them up. The idea is to let the AI handle the organization, simplifying the process of knowledge management. A key tool mentioned is the agent-browser, a free CLI tool that allows the AI to scrape content from the web directly into the raw folder. This eliminates the need for manual copy-pasting and can handle complex web pages that traditional methods struggle with. Spisak emphasizes the importance of a schema file (CLAUDE.md), which defines how the AI should organize and interpret the gathered information. Users can then instruct the AI to compile a structured wiki from the raw material, linking related topics and summarizing content, making it easy to navigate. Once the wiki is set up, users can ask the AI questions that draw from the entire knowledge base, allowing for insights and informed decisions based on collected material. Spisak recommends running monthly health checks to catch any contradictions or gaps in the knowledge base, ensuring the information remains accurate and useful. The entire setup can function without any fancy applications, relying instead on basic text files and a clear folder structure, which many find more effective than using elaborate tools like Obsidian.
