It helps turn Google Sheets entries into complete LinkedIn posts, including text, image prompts, and AI-generated images.\n\n## What it does / How it works\nThe workflow monitors a Google Sheet for new campaign entries. When a row is added, it automatically collects details about the campaign, searches LinkedIn via Tavily to identify relevant trends, and turns the information into an AI-generated LinkedIn post using a local Ollama model or an LLM of your choice.\nA second approval step lets you refine the text directly inside the sheet. Once approved, the workflow generates an image prompt, creates a ready-to-post visual with OpenAI Images, and finally publishes the post to LinkedIn.\n\n## How to set up\n\u2022 Add your own Google Sheets Trigger credentials.\n\u2022 Add Tavily, Ollama/OpenAI, and LinkedIn OAuth credentials.\n\u2022 Replace the sample Sheet URL with your own.\n\u2022 Set your LinkedIn account/person ID in the posting node.\n\n## Requirements\n\u2022 Google Sheets account\n\u2022 LinkedIn OAuth app\n\u2022 Tavily API key\n\u2022 Ollama (local) or OpenAI image generation\n\n## How to customize\nYou can change:\n\u2022 AI model\n\u2022 Image generation provider\n\u2022 Search query logic\n\u2022 Content tone\n\u2022 Approval step (manual or automatic)"
