n8n Workflow Generator inside n8n v1.0.0

🛠️ Workflow Generator in n8n – v1.0.0

This AI-native workflow enables users to generate and deploy fully functional n8n workflows just by submitting a chat prompt. Ideal for automation professionals and teams who want to rapidly build workflows without manual node configuration.

Inspired by: Mark Kashef’s “AI builds n8n Workflows FOR YOU”
A brilliant demo of how Claude AI can supercharge your automation workflow generation.

💡 Key Features:

• Chat-Based Input: Triggered by a user message using the ChatTrigger node.
• AI-Powered Workflow Creation: Uses a custom AI Agent trained with the n8n Cheat Sheet to generate valid workflow JSON.
• Memory Retention: Maintains chat history using the Simple Memory node for coherent multi-turn conversations.
• JSON Validation: Validates and parses the output to ensure proper format before deployment.
• One-Click Deployment: Automatically creates the workflow in your n8n instance via the n8n node.

⚙️ How to Set It Up:

1. Import the Workflow JSON into your n8n instance.
2. Set up the following credentials:
   • OpenAI API: Used by the OpenAI Chat Model node (e.g., GPT-4o or o3-mini). Required to generate the workflow logic.
   • n8n API: Grants permission to deploy the generated workflow directly into your n8n instance.
3. Enable Webhook URL (if using n8n.cloud): Copy the Webhook URL from the ChatTrigger node and configure it in your chatbot interface (or test via Postman).
4. Customize the AI Agent (Optional): You can modify the system prompt inside the AI Agent node to better suit your use case, such as limiting tools or focusing on specific platforms (Slack, Airtable, etc.).

🧠 Pro Tip:

The AI agent is designed to:

• Think independently using intelligent defaults.
• Add AI logic where needed (e.g., LangChain agents).
• Format output in valid, import-ready n8n JSON.
• Avoid placeholders like API_KEY_HERE — it prefers environment variables or credentials references like {{ myCredentials }}.
