DO NOT ADD THE TITLE INSIDE THE CONTENT\n\n# REQUIREMENTS\n– Use strong, emotional, or benefit-driven language.  \n– Avoid generic or vague ideas.  \n– It must be scroll-stopping, controversial, or create “fear of missing out”.  \n– Don’t use quotation marks in your output.\n- Don't add the title inside content\n- Do not include the title or slide numbers inside the content.\n- No Emojis\n\n# STYLE\n- Humanize\n– Write like a founder who’s confident and tactical.\n– Use bold, short, no-fluff lines.\n– Avoid hashtags or emojis unless they add emphasis.\n– Each carousel should feel like “value + punchline”.\n\n# OUTPUT\nYou SHOULD always output the following format, where `id` contains the video id returned by the tool call. Leave `id` as an empty string \"\" if you did not make a carousel:\n\nAlways respond in the following structured JSON:\n{\n\t\"output\": \"Output from AI\",\n        \"caption\": \"Long carousel caption, explain each tools detaily\",\n        \"title\": \"Short carousel title, 8 words max\",\n\t\"id\": \"\"\n}"

Finding appealing ideas or topics that act as a **viral hook**.\n2.  Creating text for each slide with a consistent, punchy, and **engaging style**.\n3.  Manually designing the graphics for every slide.\n4.  Writing detailed captions and an effective **Call-to-Action (CTA)**.\n5.  The manual process of posting the content to social media.\n\n## 💡 Solution\n\nAutomate the entire **Instagram Carousel** creation and posting process using a combination of **n8n, an AI Agent (GPT-4.1),** and **Blotato** as the visual creation tool.\n\nThis workflow automatically performs the following steps:\n1.  Generates a **scroll-stopping topic idea** from the initial input topic.\n2.  Uses the **AI Agent** (acting as an Alex Hormozi/Dan Koe-style copywriter) to create the multi-slide content (text, caption, and title).\n3.  Sends the generated text to **Blotato** to automatically render a series of Carousel images.\n4.  Waits for the images to be completed.\n5.  Automatically posts the final Carousel and its accompanying caption to Instagram using the **Blotato** Instagram node.\n\n## 🔭 Scope\n\nThis workflow covers:\n* **Input/Trigger:** A recurring schedule set by the **Schedule Trigger** node.\n* **Idea Generation:** Generates a captivating title and content hook using a **LangChain Agent** with OpenAI.\n* **Text Content Creation:** Generates text for each slide, the carousel title, and a long, detailed caption.\n* **Visual Creation:** Uses the **Blotato Tool** (\"Simple tweet cards monocolor\") to render the text into a series of Carousel images (set to the **4:5** aspect ratio).\n* **Status Check:** Employs the **Wait** and **If** nodes to ensure the Carousel images in Blotato have a status of `done` before proceeding to post.\n* **Posting:** Automatic posting to the connected Instagram account via the **Blotato** Instagram node.\n\n## 👤 For Who\n\nThis workflow is perfect for:\n* **Social Media Managers** or **Content Creators** who need to consistently increase the volume of high-quality, high-impact visual content.\n* **Small and Medium Enterprises (SMEs)**, especially those in *Coaching, Consulting, Digital Marketing,* or *SaaS* that rely on fast, educational, or inspirational content.\n* **AI Agent Developers** (like yourself) looking to build and demonstrate a powerful, end-to-end marketing content automation solution with n8n.\n\n## 🛠️ How to Set Up\n\nTo successfully run this workflow, you need valid credentials and specific configurations in several nodes:\n\n## 1. Credentials\n\nEnsure you have valid credentials set up in n8n for:\n* **OpenAI API:** To connect to the **OpenAI Chat Model** node (required by both AI Agents).\n* **Blotato API:** To connect to all **Blotato** nodes (`Simple tweet cards monocolor`, `Get carousel`, `Instagram [BLOTATO]`).\n\n## 2. Key Node Configuration\n\n| Node | Parameter to Note | Note |\n| :--- | :--- | :--- |\n| **Schedule Trigger** | `Rule` | Set the desired posting frequency (e.g., daily, weekly). |\n| **Topic** | `topic` | Replace the current expression value `\"=Top ai tools for finance\"` with your default or desired initial topic. |\n| **OpenAI Chat Model** | `Model` | Currently set to `gpt-4.1-mini`. Adjust this to another model (e.g., `gpt-4o` or `gpt-3.5-turbo`) based on your performance and cost requirements. |\n| **AI Agent Carousel Maker** | `System Message` | Review and adjust the **# STRUCTURE**, **# REQUIREMENTS**, and **# STYLE** sections in the AI Agent's *System Message* if you need to refine the persona, writing style, or output format. |\n| **Simple tweet cards monocolor (Blotato Tool)**| `templateInputs` | Adjust `authorName`, `handle`, and `profileImage` to match your brand's or personal account details for personalized visuals. |\n| **Wait** | `Amount` & `Unit` | The current wait time is set to **3 minutes** to allow Blotato to finish rendering the Carousel. Adjust only if you observe rendering times are consistently faster or slower. |\n| **Instagram [BLOTATO]** | `accountId` | Select the specific Instagram account that is connected via your Blotato credentials. |"
