Description
š Turn your random ideas into concrete automation specs
This workflow acts as your interactive "n8n Consultant." Simply write down a rough automation idea in Google Tasks (e.g., "Send weather updates to Telegram"), and the AI will research, design, and send a detailed n8n implementation plan to your Slack.
āØ Why is this workflow special?
Unlike simple notification workflows, this features a Human-in-the-Loop review process. You don't just get a message; you get control.
Regenerate:** Not satisfied with the AI's plan? Click a button in Slack to have the AI rewrite it instantly.
Archive:* Happy with the plan? Click "Approve" to automatically save the detailed specs to *Google Sheets** and mark the task as complete.
How it works
Fetch: The workflow periodically checks a specific Google Tasks list for new ideas.
AI Design: The AI (OpenAI) analyzes your idea and generates a structured plan, including node configuration and potential pitfalls.
Human Review: It sends the plan to Slack with interactive "Approve" and "Regenerate" buttons. The workflow waits for your input.
If Regenerate: The AI re-analyzes the idea and creates a new variation.
If Approve: The workflow proceeds to the next step.
Archive: The approved plan (Title, Nodes, Challenges) is saved to a Google Sheet for future development.
Close: The original Google Task is updated with a "Processed" flag.
