n8n Workflow Builder AI is an open-source Chrome Extension that leverages a sophisticated multi-agent AI system to help you generate n8n workflow and node configurations using natural language prompts. Our system uses three specialized AI agents working in sequence - a Planner, an Architect, and a Validator - to ensure high-quality, accurate workflow generation. Additionally, a Voice Assistant agent powered by Gemini Live API provides real-time screen-sharing guidance.

└───────────────────────────────────────────────────────────────┘
Create a workflow: Start with a Schedule trigger running every Monday
at 9 AM. Then, use an HTTP Request node to GET data from
'https://api.example.com/users'. Finally, use a Set node to extract
only the 'email' field from the result.
Generate an n8n Google Sheets node to append a row to spreadsheet ID
'YOUR_SHEET_ID' on sheet 'Sheet1'. The row should contain columns
'Name' with value '{{ $json.name }}' and 'Timestamp' with value
'{{ $now }}'.
Build a workflow that monitors a Gmail inbox every 5 minutes, extracts
attachments from new emails, uploads them to Google Drive, and sends
a Slack notification with the file link.
✅ Do:
- Be specific about node types and parameters - helps Planner agent
- Include actual URLs, IDs, or field names - improves Architect accuracy
- Mention n8n expression syntax when needed (e.g.,
{{ $json.field }}) - Specify trigger schedules clearly - reduces validation errors
- Request specific node configurations
- Trust the validation report - it's AI-verified
❌ Don't:
- Use vague descriptions - wastes agent processing time
- Assume default values without stating them
- Mix multiple unrelated workflows in one prompt
- Forget to specify required credentials or authentication
- Ignore validation warnings - they're there for a reason
The Voice Assistant is a breakthrough feature that combines:
- Real-time voice interaction using Gemini's Live API
- Screen sharing to see exactly what you're working on
- Context awareness of your n8n workflows and extension state
- Step-by-step guidance for complex tasks
| Feature | Description |

| 👁️ Screen Awareness | Sees your n8n canvas and extension interface |
| 🗣️ Natural Conversation | Talk naturally, ask questions, get instant answers |
| 📍 Contextual Help | Understands where you are in the workflow process |
| 🎯 Task Guidance | Walks you through pasting, configuring, and debugging |
| 🔍 Workflow Explanation | Explains generated JSON in plain language |
| 🐛 Debugging Support | Helps troubleshoot workflow issues |
| 📚 n8n Knowledge | Answers questions about n8n nodes and features |
First-Time Users:
You: "I've never used n8n. How do I paste this workflow?"
Assistant: "I can see your n8n canvas. Let me guide you. Right-click
anywhere on the canvas..."
Debugging:
You: "My workflow isn't working."
Assistant: "I see your workflow. The HTTP Request node isn't connected
to the Set node. Let me show you how to fix that..."
Learning:
You: "What's the difference between Set and Code nodes?"
Assistant: "Great question! Set nodes are for simple data transformations,
while Code nodes allow JavaScript/Python..."
