Description

šŸš€ 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. ✨ 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. How to set up Google Tasks: Create a new list named "n8n Ideas". Google Sheets: Create a new sheet with the following headers in the first row (A to H): Date Added Idea Title Status Recommended Nodes Key Challenges Improvement Ideas Alternatives Source Task ID Credentials: Configure credentials for Google Tasks, Google Sheets, OpenAI, and Slack. Configure Nodes: [Step 1] Fetch New Ideas: Select your Task list. [Step 4] Slack — Review & Approve: Select your target channel. [Action] Archive to Sheets: Select your Spreadsheet and Sheet. [Close] Mark Task Done: Select your Task list again. Requirements Google Tasks account Google Sheets account OpenAI API Key Slack account. An n8n automation workflow template by Shun Nakayama.
