"description": "\n## This n8n template helps you build a full AI-powered LinkedIn content generator with just a few clicks. \n\nPaired with the [free WeWeb UI template](https://go.weweb.io/zoYeg5g), it becomes a ready-to-use web app where users can:\n- Add their own OpenAI API key \n- Customize the prompt and define 6 content topics \n- Edit the AI-generated topics \n- Choose when to generate LinkedIn posts, complete with hashtags and an optional image\n\n## Who This Is For\nPerfect for marketers, indie hackers, and solopreneurs who want to build their personal brand on LinkedIn while staying in control of what gets posted.\n\n---\n\n## \ud83e\udde0 What Makes This Different\n\nUnlike most AI agents, **you stay fully in control**:\n- You define the tone and focus via the prompt.\n- You choose which topics to keep or modify.\n- You decide when to generate a post.\n- You can build on top of this and create your own SaaS product.\n\nIt\u2019s also **modular and extendable**\u2014hook it up to your backend, add user login, or feed AI improvements based on user input.\n\n---\n\n## \u2699\ufe0f How It Works\n1. **Triggering Events**: The app includes 3 pre-configured triggers, ready to be hooked into your WeWeb frontend. Just update the webhook URLs after duplicating the n8n workflow.\n2. **Topic Generation**: A call is made to OpenAI (GPT-4) to generate topic ideas based on your prompt.\n3. **Post Creation**: Once topics are approved or edited, GPT-4 writes full posts with suggested hashtags.\n4. **Image Generation** *(Optional)*: If enabled, a DALL\u00b7E call generates a relevant image.\n5. **Everything Stays Local**: All data and images are handled locally, no cloud storage setup needed.\n\n---\n\n## \ud83e\uddea Requirements & Setup\nNo fancy infrastructure required. Here\u2019s what helps you get started:\n- **Free WeWeb account** (recommended) to use the frontend UI template \n- **OpenAI account** with API access (for GPT-4 and DALL\u00b7E) \n- **n8n account** (self-hosted or cloud) to run the backend workflow \n\nThe template is **completely free** to use. Since each user adds their own OpenAI API key, you don't need to worry about usage costs or rate limits on your end.\n\n---\n\n## \ud83d\udd27 Want to Go Further?\nThis setup is beginner-friendly, but developers can:\n- Add user accounts \n- Save post history \n- Feed user feedback back into the prompt logic \n- Launch their own branded version as a SaaS",

The interface includes three screens:\n1. Create topics\n2. Edit topics and generate posts\n3. Edit posts and generate images\n\nEach screen has its own dedicated webhook. This ensures users are 100% in control of the content that\u2019s generated and published to their LinkedIn account.\n\nIf you'd like to connect this n8n template directly to a WeWeb UI, it's possible. The WeWeb template is available for free [right here](https://go.weweb.io/zoYeg5g). "
