Welcome to Your Second Brain

This is your AI-powered personal knowledge management system.

What is a Second Brain?

A Second Brain is an external, digital system for capturing, organising, and sharing ideas, insights, and information. The concept was popularised by Building a Second Brain by Tiago Forte.

By externalising your thinking, you:

• Free up mental RAM for creative work
• Build a personal knowledge base that compounds over time
• Make connections between ideas you might otherwise miss

How This System Works

Your notes live in this Markdown vault — fully compatible with Obsidian and Logseq.

The AI layer:

1. Ingests every Markdown file automatically
2. Embeds content into vector space for semantic search
3. Links related documents autonomously
4. Tags untagged documents using an LLM
5. Summarises long documents for quick reference

Getting Started

1. Add Markdown files to this vault
2. Use [[WikiLinks]] to connect ideas
3. Add YAML frontmatter for structured metadata
4. Search your knowledge at http://localhost:3000/search
5. Chat with your notes at http://localhost:3000/chat

Folder Structure

• projects/ — Active projects
• resources/ — Reference material and research
• areas/ — Ongoing areas of responsibility

Tips

• Use #tags inline or in frontmatter
• [[WikiLinks]] create automatic knowledge graph edges
• The AI agents run in the background — check the graph view after a few minutes
