Description

This AI Agent Carousel Maker uses ChatGPT and Blotato to write, generate, and auto-post social media carousels to 5 social platforms: Instagram, Tiktok, Facebook, Twitter, and Pinterest.

Simply chat with the AI agent, confirm which prebuilt viral carousel template you want to use, then the AI Agent populates the template with your personalized information and quotes, and posts to social media on autopilot.

Who Is This For?

This is perfect for entrepreneurs, small businesses, content creators, digital marketing agencies, social media marketing agencies, and influencers.

How It Works

1. Chat: AI Agent Carousel Maker

  • Chat with AI agent about your desired carousel
  • Confirm quotes and carousel template to use

2. Carousel Generation

  • AI agent calls corresponding Blotato tool to generate carousel
  • Wait and fetch completed carousel

3. Publish to Social Media via Blotato

  • Choose your social accounts
  • Either post immediately or schedule for later

Setup

  • Sign up for OpenAPI API access and create credential
  • Sign up for Blotato.com
  • Generate Blotato API Key by going to Settings > API > Generate API Key (paid feature only)
  • Create Blotato credential
  • If you're using n8n, ensure you have ""Verified Community Nodes"" enabled in your n8n Admin Panel. Then, install ""Blotato"" verified community node.
  • Click ""Open chat"" to test workflow
  • Complete SETUP sticky notes in BROWN in this template

Tips & Tricks

  • AFTER your first successful run, open each carousel template tool call (i.e. pink nodes attached to AI Agent Carousel Maker) and tweak the parameters, but DO NOT change the ""quotes"" parameter unless you're an n8n expert.
  • DO NOT edit the 'quotes' parameter unless you're an n8n expert.
  • When adding a new template, DO NOT duplicate an existing node. Instead, click '+ Tool' > Blotato Tool > Video > Create > select new template. This ensures template parameters are correctly loaded.
  • While testing: enable only 1 social platform, and deactivate the rest. Add optional parameter 'scheduledTime' so that you don't accidentally post to social media. Check your content calendar here: https://my.blotato.com/queue/schedules

n8n Workflow: AI-Powered Social Media Carousel Creator & Poster

This n8n workflow leverages AI to generate and manage social media carousel content, allowing for human review before publishing across multiple platforms. It's designed to streamline the content creation process for social media managers and marketers.

What it does

This workflow automates the following steps:

  1. Listens for Chat Messages: It starts by triggering when a new chat message is received, likely initiating a content creation request.
  2. Generates AI Content: An AI Agent, powered by an OpenAI Chat Model and a Simple Memory, processes the chat message to generate social media carousel content. This agent can understand context and produce relevant content.
  3. Routes for Review: The generated content is then routed through an "If" node, which likely checks for certain conditions (e.g., content quality, specific keywords) to determine if it requires human review or can proceed directly.
  4. Human-in-the-Loop Approval: If human intervention is required, the workflow pauses and waits for a human to review and approve the content via a "Chat" node. This ensures quality control and brand alignment.
  5. Merges Approved Content: Once approved (or if no approval was needed), the content is merged to continue the workflow.
  6. Waits (Optional Delay): An optional "Wait" node can introduce a delay, which might be used for scheduling posts or allowing buffer time.
  7. Posts to Social Media (Implicit): While not explicitly defined in the provided JSON, the overall structure and the directory name ("create--post-social-media-carousels-across-5-platforms") strongly suggest that subsequent nodes would handle posting the approved carousel content to various social media platforms.

Prerequisites/Requirements

To use this workflow, you will need:

  • n8n Instance: A running n8n instance.
  • OpenAI API Key: For the OpenAI Chat Model to generate content.
  • LangChain Integration: The n8n LangChain nodes (@n8n/n8n-nodes-langchain) must be installed and configured in your n8n instance.
  • Chat Platform Integration: The "Chat Trigger" and "Chat" nodes imply integration with a chat platform (e.g., Slack, Telegram, Discord) where the workflow can receive and send messages for content requests and approvals.
  • Social Media Platform Credentials (Implicit): To post the carousels, you would need credentials for the target social media platforms (e.g., Facebook, Instagram, LinkedIn, Twitter, Pinterest). These nodes are not in the provided JSON but are essential for the full functionality implied by the workflow's name.

Setup/Usage

  1. Import the Workflow: Import the provided JSON into your n8n instance.
  2. Configure Credentials:
    • Set up your OpenAI API key as a credential for the "OpenAI Chat Model" node.
    • Configure the "Chat Trigger" and "Chat" nodes with the appropriate credentials for your chosen chat platform.
    • (Implicit) Configure credentials for your social media platforms in the subsequent nodes (not included in this JSON).
  3. Configure AI Agent: Adjust the "AI Agent" and "OpenAI Chat Model" settings to fine-tune the content generation based on your specific needs and brand guidelines.
  4. Define "If" Conditions: Customize the "If" node to set the conditions under which content requires human review.
  5. Activate the Workflow: Once configured, activate the workflow. It will start listening for chat messages to initiate the carousel creation process.
  6. Initiate via Chat: Send a message to your configured chat platform to trigger the workflow and request social media carousel content.
  7. Review and Approve: If prompted, review the AI-generated content in your chat platform and provide approval to proceed with publishing.

Automated UGC video generator with Gemini images and SORA 2

This workflow automates the creation of user-generated-content-style product videos by combining Gemini's image generation with OpenAI's SORA 2 video generation. It accepts webhook requests with product descriptions, generates images and videos, stores them in Google Drive, and logs all outputs to Google Sheets for easy tracking. Main Use Cases Automate product video creation for e-commerce catalogs and social media. Generate UGC-style content at scale without manual design work. Create engaging video content from simple text prompts for marketing campaigns. Build a centralized library of product videos with automated tracking and storage. How it works The workflow operates as a webhook-triggered process, organized into these stages: Webhook Trigger & Input Accepts POST requests to the /create-ugc-video endpoint. Required payload includes: product prompt, video prompt, Gemini API key, and OpenAI API key. Image Generation (Gemini) Sends the product prompt to Google's Gemini 2.5 Flash Image model. Generates a product image based on the description provided. Data Extraction Code node extracts the base64 image data from Gemini's response. Preserves all prompts and API keys for subsequent steps. Video Generation (SORA 2) Sends the video prompt to OpenAI's SORA 2 API. Initiates video generation with specifications: 720x1280 resolution, 8 seconds duration. Returns a video generation job ID for polling. Video Status Polling Continuously checks video generation status via OpenAI API. If status is "completed": proceeds to download. If status is still processing: waits 1 minute and retries (polling loop). Video Download & Storage Downloads the completed video file from OpenAI. Uploads the MP4 file to Google Drive (root folder). Generates a shareable Google Drive link. Logging to Google Sheets Records all generation details in a tracking spreadsheet: Product description Video URL (Google Drive link) Generation status Timestamp Summary Flow: Webhook Request → Generate Product Image (Gemini) → Extract Image Data → Generate Video (SORA 2) → Poll Status → If Complete: Download Video → Upload to Google Drive → Log to Google Sheets → Return Response If Not Complete: Wait 1 Minute → Poll Status Again Benefits: Fully automated video creation pipeline from text to finished product. Scalable solution for generating multiple product videos on demand. Combines cutting-edge AI models (Gemini + SORA 2) for high-quality output. Centralized storage in Google Drive with automatic logging in Google Sheets. Flexible webhook interface allows integration with any application or service. Retry mechanism ensures videos are captured even with longer processing times. --- Created by Daniel Shashko
