🧠 AI-Powered Second Brain

Describe yourself in prd.md → run one command → get a full personalized Obsidian vault

An AI-powered generator that builds your personal Cognitive Operating System — a complete Obsidian vault tailored to you, ready for AI collaboration and self-growth.

🎯 What is This?

This is an AI-powered vault generator that creates a complete Cognitive Operating System (Cognitive OS) personalized to you. Define who you are in a prd.md spec, run a single command in Cursor, and get a fully structured Obsidian vault — profile pages, review templates, AI collaboration prompts, and all.

⚠️ What this is NOT: This is not a generic notes app or a static template you fill in by hand. It is a generator — your prd.md drives the output.

🧠 Core Philosophy

Cognitive OS = Your Brain + Obsidian (Memory Container) + AI (External Brain) + Structured Profile (System Configuration)

• 🧠 External Brain: Treat AI as your external cognitive processor
• 💾 Memory Container: Obsidian serves as your long-term memory storage
• ⚙️ System Configuration: Structured profile defines your cognitive architecture
• 🔄 Cognitive Loop: Complete cycle of "Input → Process → Store → Output → Feedback"

✨ Key Features

🪄 Zero-Template, One-Command Generation

• Use Cursor's /gov: GenerateObsidianVault command to dynamically generate complete cognitive architecture
• Rule-driven generation based on your PRD configuration
• No manual template maintenance required

🏗️ Complete Personal Profile System

• 10 structured profile pages covering all aspects of personal development
• Bidirectional linking for knowledge connections
• Comprehensive templates with guiding questions
• Tag-based organization for easy navigation

🤖 AI Collaboration Ready

• Claude Code direct vault access — Claude reads and writes vault files natively from the terminal
• AI profile summary template for Claude Code and ChatGPT integration
• Structured data for personalized AI interactions
• Context-rich information for effective AI collaboration
• Growth tracking for AI-assisted development

📈 Growth & Development Focused

• Regular review templates (daily, weekly, monthly, quarterly)
• Progress tracking across all life areas
• Reflection prompts for deeper insights
• Goal management with SMART framework

🚀 Quick Start

1. Open Cursor and create a new project
2. Place your prd.md in the project (customize it to describe yourself)
3. Run the command: /gov: GenerateObsidianVault
4. Cursor automatically generates the complete vault structure
5. Open the generated obsidian-vault/ folder in Obsidian — done!

Alternative: Manual Setup (use the included vault as-is)

1. Clone this repository
2. Import the obsidian-vault/ folder into Obsidian
3. Follow the SETUP-GUIDE.md for complete instructions
4. Start filling out your profile systematically

🤝 AI Collaboration Workflow

1. Profile Development

• Fill out your profile pages systematically
• Add specific examples and details
• Use internal links to connect related information

2. AI Summary Creation

• Use the AI profile summary template
• Customize based on your specific needs
• Update regularly as your profile evolves

3. AI Integration

Method: Claude Code Direct Vault Access (Recommended)

Claude Code can work directly on your vault folder via the terminal — no copy-pasting required:

cd ~/your-obsidian-vault   # replace with your actual vault path
claude
# Claude Code can now directly read/write all vault files

Install: Claude Code documentation — CLI install, setup, and first run.

• When you run Claude Code from your vault directory, it can read and update multiple files there (like any local CLI tool; session limits apply).
• It can read, write, and reorganize files in that folder based on your prompts and tool permissions.
• Run multi-file refactors (e.g., updating all profile pages at once).
• Treat your vault path as sensitive: anything under that folder may be readable when the tool accesses your files.

Alternative: ChatGPT Custom Instructions

• Copy your profile summary and add it to ChatGPT Custom Instructions
• Share relevant sections for specific AI interactions

General

• Document AI insights in your diary

4. Continuous Growth

• Regular profile reviews and updates
• Track progress and insights
• Evolve your cognitive architecture
