How to Build AI Agents From YouTube Tutorials

No manual node building. No guesswork. Just copy-paste.

This guide shows you how to turn any n8n YouTube tutorial into a fully working AI agent using Google AI Studio and Claude, without rebuilding anything from scratch.

What You'll Need

Step 1: Extract the Workflow from YouTube

Tool: Google AI Studio (Gemini)

Google AI Studio can process YouTube videos directly, no transcripts needed.

How to do it:

1. Go to aistudio.google.com

2. Start a new chat with Gemini 3 Pro (or latest model with video understanding)

3. Paste your YouTube tutorial link

4. Use this prompt:

Analyze this n8n tutorial video and break down the complete workflow:

1. List every node used (in order)
2. For each node, specify:
   - Node type (HTTP Request, AI Agent, Code, etc.)
   - Configuration settings shown
   - Connections to other nodes
3. Include any API endpoints, credentials, or parameters mentioned
4. Note the trigger type (Manual, Webhook, Schedule, etc.)

Be extremely detailed—I need to recreate this workflow exactly.

Example Output You'll Get:

WORKFLOW BREAKDOWN: AI Email Responder Agent

TRIGGER: Manual Trigger
↓
NODE 1: Gmail Trigger
- Type: Gmail Trigger
- Settings: Poll every 5 minutes, Label: "Inbox"
↓
NODE 2: AI Agent
- Type: AI Agent (Tools Agent)
- Model: GPT-4
- System Prompt: "You are an email assistant..."
- Tools connected: Gmail Send
↓
NODE 3: Gmail Send
- Type: Gmail
- Operation: Send Email
...

Step 2: Convert to n8n JSON with Claude

Tool: Claude (with a Custom Project)

Now you'll turn that breakdown into importable JSON.

Setting Up Your Claude Project (One-Time Setup):

1. Go to claude.ai → Projects → Create Project

2. Name it: n8n Workflow Generator

3. Add these Project Instructions:

You are an n8n workflow expert. When given a workflow breakdown, you convert it into valid n8n JSON format that can be directly imported.

RULES:
- Output ONLY valid JSON (no markdown, no explanation)
- Use correct n8n node type names (e.g., "n8n-nodes-base.gmail", "n8n-nodes-langchain.agent")
- Include proper node positions for clean visual layout
- Set up all connections between nodes
- Include placeholder values for credentials (user will configure)
- Use the latest n8n node versions

STRUCTURE:
{
  "name": "Workflow Name",
  "nodes": [...],
  "connections": {...},
  "settings": {...}
}

How to Generate the JSON:

1. Open your Claude Project

2. Paste the workflow breakdown from Step 1

3. Add this prompt:

Convert this workflow breakdown into n8n-importable JSON:

[PASTE GEMINI OUTPUT HERE]

Output only the JSON, nothing else.

Step 3: Import Into n8n

Tool: n8n (Cloud or Self-Hosted)

Import Steps:

1. Open n8n → Create New Workflow

2. Click the three dots (⋮) in the top-right corner

3. Select Import from JSON

4. Paste your JSON from Step 2

5. Click Import

Your entire workflow appears instantly—all nodes connected.

Step 4: Configure & Test

Credential Setup:

For each service in your workflow, add credentials:

1. Click a node with a warning

2. Select Create New Credential

3. Follow the OAuth flow or paste API keys

Common credentials you'll need:

• Gmail/Google: OAuth2 (requires Google Cloud Console setup)

• OpenAI: API Key from platform.openai.com

• Anthropic: API Key from console.anthropic.com

• Slack: OAuth2 or Bot Token

Test Your Workflow:

1. Click Test Workflow (play button)

2. Check each node's output (click to expand)

3. Fix any errors (usually missing fields or credentials)

4. Once working → Activate the workflow

Pro Tips

Improve Gemini's Video Analysis

If Gemini misses details, try:

Go through the video again at these timestamps and extract:
- [0:00-2:00] What trigger is used?
- [2:00-5:00] What are the exact AI Agent settings?
- [5:00-8:00] What tools/sub-nodes are connected?

Be specific about every dropdown selection and text field shown.

Make Claude's JSON More Reliable

Add to your project instructions:

Before outputting JSON:
1. Validate all node type names exist in n8n
2. Ensure all connections reference existing node names
3. Check that typeVersion matches current n8n versions

Handle Complex Multi-Branch Workflows

For workflows with IF nodes, loops, or multiple branches:

For this workflow, also include:
- All conditional branches (IF true/false paths)
- Loop configurations (batch size, iterations)
- Error handling nodes
- All sub-workflows or nested agents

Summary

Total: ~10 minutes from YouTube video to working agent.
