# 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

- `daily/` — Daily notes and journals
- `projects/` — Active projects
- `resources/` — Reference material and research
- `areas/` — Ongoing areas of responsibility
- `templates/` — Note templates

## 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
