Add Your OpenAI Credential\n- Go to **Credentials > OpenAI API**.\n- Paste your API key and save.\n- Make sure your model is set to `gpt-4.1` or similar.\n\n### 2. Workflow Logic\n- The `idea` is sent to an **AI Agent node**.\n- The prompt instructs the AI to generate a short, emoji-rich LinkedIn caption.\n- A **Parser node** structures the JSON output to extract just the caption.\n\n### 3. Save Caption\n- The AI-generated caption is written back to the Google Sheet in the `caption` column.\n- The `complete` column is also updated to “Yes”.\n\n---"
