🎨 TikTok Carousel Replicator & Translator

An end-to-end automation system that monitors TikTok accounts for new 3-image carousel posts, extracts text overlays and visual layouts using AI vision analysis, translates content into English, and automatically regenerates brand-new carousel images ready for review and posting.

What It Does

This workflow eliminates the manual process of:

  • Daily monitoring for new carousel content
  • Screenshot capture and image extraction
  • Text transcription and translation
  • Layout recreation in design tools
  • Manual formatting and brand consistency checks

Instead, it delivers 3 production-ready images to your inbox every morning—complete with translated text, matched composition, and side-by-side comparisons for quick approval.

Key Features

  • Automated Daily Monitoring - Checks target TikTok accounts on schedule
  • AI-Powered Vision Analysis - Extracts text, layout, and composition with Gemini Vision
  • Smart Translation - Converts text to natural English while preserving intent
  • Intelligent Image Generation - Recreates carousels with Midjourney/DALL-E based on analyzed layouts
  • Review Dashboard - Organized Google Sheets with original vs. new comparisons
  • Email Notifications - Morning digest with clickable previews

Who It's For

Content creators, social media managers, and marketing teams who need to adapt high-performing carousel content from other languages into English—without spending hours in Canva every day.

Time Saved

From 3+ hours of manual work → 2 minutes of review per carousel set.

Workflow Breakdown

Monitor → Extract & Analyze → Translate → Generate → Review & Deliver

Each section runs automatically, processing images sequentially and delivering organized results to your review dashboard with email notifications.

🚀 SETUP INSTRUCTIONS

Required Credentials:

  1. Google Gemini API - For vision analysis
  2. Midjourney API (or alternative: DALL-E, Stable Diffusion)
  3. OpenAI API - For prompt generation and translation enhancement
  4. Google Sheets - For review dashboard
  5. Gmail - For notifications

Configuration Steps:

  1. Replace @USERNAME in TikTok RSS node with target account
  2. Set your Google Sheet ID in "Save to Review Sheet" node
  3. Update email addresses in notification node
  4. Test with a single post before enabling daily schedule

Alternative Approaches:

  • Can use TikTok API instead of RSS (if available)
  • Can use Canva API instead of Midjourney for generation
  • Can integrate with Airtable for more advanced review workflows
  • Can add approval workflow with interactive buttons

n8n Auto-Translate & Recreate TikTok Carousels with Gemini Vision & Midjourney

This n8n workflow automates the process of generating translated content and images for TikTok-style carousels, leveraging AI for creative tasks and human-in-the-loop (HITL) for review. It's designed to streamline content creation for multi-language social media campaigns, particularly for visual platforms like TikTok.

What it does

This workflow orchestrates a series of steps to create localized carousel content:

  1. Triggers on Schedule: The workflow starts on a defined schedule, regularly checking for new content to process.
  2. Fetches Content from Google Sheets: It reads data from a specified Google Sheet, likely containing original content, image URLs, and translation status.
  3. Filters for Untranslated Content: It checks if the content has already been processed (translated and images generated). Only items marked as "not translated" proceed.
  4. Generates Image Descriptions (English): For each untranslated item, it uses an OpenAI model to generate a detailed English description of the original image, suitable for image generation prompts.
  5. Generates Midjourney Prompts: It then uses another OpenAI model to transform the English image description into a Midjourney-compatible prompt, ensuring high-quality image generation.
  6. Translates Content to Target Language: The workflow translates the original content into a target language using an OpenAI Chat Model.
  7. Generates Translated Image Descriptions: It translates the English image description into the target language using an OpenAI Chat Model.
  8. Generates Translated Midjourney Prompts: It translates the Midjourney prompt into the target language using an OpenAI Chat Model.
  9. Generates Images with Gemini Vision: It uses Google Gemini to generate new images based on the translated Midjourney prompts.
  10. Aggregates Generated Content: All the generated translations, prompts, and image URLs are collected.
  11. Sends for Human Review (Gmail): The aggregated content (original, translated, and generated image links) is sent via Gmail for human review and approval.
  12. Waits for Approval: The workflow pauses, awaiting a response to the approval email.
  13. Processes Approval/Rejection: Based on the human review, the workflow either proceeds with approved content or marks rejected content for re-evaluation.
  14. Updates Google Sheet: Finally, it updates the Google Sheet with the translated content, generated image URLs, and the status (translated/approved).

Prerequisites/Requirements

To use this workflow, you will need:

  • n8n Instance: A running n8n instance.
  • Google Sheets Account: Configured credentials for Google Sheets to read and write data.
  • OpenAI API Key: Credentials for OpenAI to access its language models (for translation and prompt generation).
  • Google Gemini API Key: Credentials for Google Gemini to access its vision capabilities for image generation.
  • Gmail Account: Configured credentials for Gmail to send approval emails.
  • Midjourney Account (Implicit): While not directly integrated for image generation within n8n, the workflow generates prompts for Midjourney, implying you would use Midjourney separately to create the images based on these prompts.
  • Understanding of LangChain nodes: Familiarity with how LangChain nodes (AI Agent, OpenAI Chat Model, Google Gemini) function within n8n.

Setup/Usage

  1. Import the Workflow: Download the provided JSON and import it into your n8n instance.
  2. Configure Credentials:
    • Set up your Google Sheets credentials.
    • Set up your OpenAI credentials.
    • Set up your Google Gemini credentials.
    • Set up your Gmail credentials.
  3. Configure Google Sheet Node (ID: 18):
    • Specify the Spreadsheet ID and Sheet Name where your original content resides.
    • Ensure your sheet has columns for original content, image URLs, and a status column (e.g., "Translated Status") that the workflow can update.
  4. Configure AI Agent (ID: 1119) and OpenAI/Gemini Nodes (IDs: 1153, 1250, 1309):
    • Review the prompts and settings within these nodes to ensure they align with your content and desired output.
    • Adjust the "Model" and "Temperature" parameters as needed for your specific use case.
  5. Configure Gmail Node (ID: 356):
    • Specify the recipient email address for the human review.
    • Customize the email subject and body to provide clear instructions for approval/rejection.
  6. Configure Wait Node (ID: 514):
    • Adjust the waiting period or conditions if necessary.
  7. Activate the Workflow: Once configured, activate the workflow. It will run according to the schedule defined in the "Schedule Trigger" node (ID: 839).

This workflow provides a robust framework for automating multi-language content creation, significantly reducing manual effort and accelerating content deployment.

If AI returns non-JSON, keep “Return only a JSON array” as the last line of the prompt and keep jsonOutput enabled. Consider adding validation on parsing.warnings to gate Salesforce writes. For discounts/taxes in OLI: Standard OLI fields don’t support per-line discount amounts directly; model them in UnitPrice or custom fields.
