AI Agent: Content to 9:16 Social Media Image Generator

Unlock Automated Social Media Visuals with this AI Agent

This AI Agent streamlines the creation of compelling 9:16 aspect ratio images for your social media channels like TikTok, Instagram Reels, and YouTube Shorts. It takes your existing content (e.g., blog posts from Airtable), leverages OpenAI to craft short video scripts and visual prompts, and then uses Leonardo.ai to generate high-quality images for each scene and a thumbnail. Finally, it organizes all generated assets by logging them into your Airtable base.

AI Agent Abilities

• Content Analysis & Scripting: Intelligently processes input content to generate concise video scripts with multiple scenes tailored for short-form video formats.
• Prompt Engineering: Creates effective image generation prompts for both scenes and thumbnails, enhancing them for optimal visual output with Leonardo.ai.
• 9:16 Image Generation: Produces images in the 9:16 aspect ratio (specifically 768x1376 pixels), ideal for vertical video platforms, using Leonardo.ai's powerful models.
• Asset Management Integration: Automatically logs generated image URLs and related metadata into Airtable for easy tracking and use.

Key Features & Benefits

• Automated Content Repurposing: Effortlessly transform long-form content into engaging visual assets for short-form video platforms.
• AI-Driven Creativity: Utilizes OpenAI (e.g., GPT-4o-mini) for scriptwriting and Leonardo.ai for stunning image generation, ensuring fresh and relevant visuals.
• Optimized for Social Media: Generates visuals in the 9:16 aspect ratio, perfect for maximizing impact on TikTok, Instagram Reels, and YouTube Shorts.
• Streamlined Workflow: Fetches content from Airtable, processes it through AI models, and saves results back to Airtable, minimizing manual intervention.
• Data Organization: Systematically stores generated assets and their details in Airtable for easy access and management.
• Scalable Visual Production: Create multiple image assets for various content pieces without significant manual design effort.

• An n8n instance (Cloud or self-hosted).
• OpenAI API Key with access to a suitable model (e.g., gpt-4o-mini or newer recommended).
• Leonardo.ai API Key.
• Airtable API Key and a configured Airtable Base with tables for content input (e.g., blog posts, brand guidelines) and asset logging. The workflow expects specific table structures; refer to the workflow notes or example base link provided by the original author (AlexK1919) if available.

1. Download the n8n workflow JSON file.
2. Import the workflow into your n8n instance.
3. Configure the Airtable nodes ('Get Brand Guidelines', 'Get SEO Keywords', 'Get Content', 'Add Asset Info', 'Add Asset Info1'): Enter your Airtable API Key (Personal Access Token recommended), Base ID, and Table IDs. Ensure your Airtable structure matches what the workflow expects for fetching content and logging assets.
4. Configure the 'Script Prep' OpenAI node: Enter your OpenAI API Key in the credentials section and select your desired model (e.g., gpt-4o-mini).
5. Configure the Leonardo.ai HTTP Request nodes (e.g., 'Leo - Improve Prompt', 'Leo - Generate Image'): a. Create or select an 'Header Auth' credential in n8n. b. For a new credential: Name it (e.g., 'LeonardoAIAuth'), use 'Authorization' as the HTTP Header 'Name', and 'Bearer YOUR_LEONARDO_AI_API_KEY' (replace with your actual key) as the 'Value'. c. Select this credential in the 'Authentication' field of each Leonardo.ai HTTP Request node.
6. Review and customize prompts: Adjust the system prompt in the 'Script Prep' OpenAI node and parameters in the 'Leo - Generate Image' nodes (like modelId, presetStyle) if needed to align with your brand or desired output style.
7. Set API limits: Be mindful of API rate limits and costs for OpenAI and Leonardo.ai. Adjust 'Wait' nodes if necessary, though the current 30-second waits are for image generation completion.
8. Test with a single content piece: Run the workflow with the 'When clicking ‘Test workflow’' trigger to ensure all connections and data flows are correct.
9. Activate the workflow. Consider replacing the manual trigger with an automated one (e.g., 'Airtable Trigger' for new content records) for continuous operation.
