AI-Powered Instagram Content Generator from Top Trends

Unlock Automated & Trending Instagram Content with this AI Agent

Tired of the content treadmill? This AI Agent is your automated partner for keeping your Instagram feed vibrant and engaging. It intelligently scours Instagram for top-performing posts based on hashtags you define (like #blender3d or #isometric), then springs into action.

Using advanced AI, it analyzes the visual essence of trending images with OpenAI's GPT-4o-mini. Next, it crafts compelling, SEO-friendly Instagram captions, complete with relevant hashtags, also using GPT-4o-mini. The real magic happens when it leverages Replicate (specifically the Flux Schnell model) to generate a brand new, unique image inspired by the trend but distinctively yours.

Finally, this agent seamlessly posts the AI-generated image and caption to your Instagram Business Account, all on a schedule you set. It even checks your PostgreSQL database to ensure no duplicate content ideas are re-processed and keeps you updated via Telegram on its progress or any hiccups.

• PostgreSQL database credentials. You'll need to create a table named top_trends using a schema like the one provided in the workflow's 'Sticky Note12' (typically includes fields like id, prompt, code, tag, isposted, thumbnail_url).
• Telegram Bot Token and the Chat ID for receiving notifications.

1. Download the n8n workflow JSON file.
2. Import the workflow into your n8n instance.
3. Configure Credentials:
   • Open the 'OpenAI' nodes ('Analyze Image and give the content', 'Analyze Content And Generate Instagram Caption') and select/create your OpenAI credentials.
   • Ensure the 'Generate image on flux' (HTTP Request) node's Authorization header uses your Replicate token (configured via the 'Replicate params' Set node output).
   • Ensure the 'get top trends on instagram' HTTP Request nodes' x-rapidapi-key header uses your RapidAPI key (configured via the 'Rapid Api params' Set node output).
   • Open the Facebook Graph API nodes ('Prepare data on Instagram', 'Check Status Of Media Before Uploaded', 'Publish Media on Instagram', 'Check status of post ') and select/create your Facebook Graph API credentials.
   • Open the PostgreSQL nodes ('Check Data on Database Is Exist', 'insert data on db') and select/create your PostgreSQL credentials.
   • Open the Telegram nodes and select/create your Telegram API credentials.
4. Set Workflow Parameters (in the correspondingly named Set nodes at the beginning of the workflow):
   • 'Replicate params': input your replicate_token.
   • 'Instagram params': input your instagram_business_account_id.
   • 'Telegram Params': input your telegram_chat_id.
   • 'Rapid Api params': input your x-rapid-api-key.
5. Database Setup: Connect to your PostgreSQL database and create the top_trends table if it doesn't exist. A sample CREATE TABLE statement is often found in a Sticky Note within the workflow (e.g., 'Sticky Note12').
6. Customize Hashtags & API Endpoints:
   • Modify the URLs and parameters in the 'get top trends on instagram #blender3d' and 'get top trends on instagram #isometric' HTTP Request nodes if you want to change hashtags or use a different Instagram scraping API.
7. Review and Tune AI Prompts:
   • Adjust the prompt in the 'Analyze Image and give the content' OpenAI node to guide image description.
   • Refine the prompt in the 'Analyze Content And Generate Instagram Caption' OpenAI node for desired caption style.
   • Modify the JSON body in the 'Generate image on flux' HTTP Request node, especially the prompt field, to control the Replicate image generation.
8. Set Schedule: Configure the 'Schedule Trigger1' node to your desired posting frequency (e.g., '5 13,19 * * *' for 1:05 PM and 7:05 PM daily, adjust timezone in workflow settings).
9. Activate the workflow and monitor the first few runs via Telegram notifications.
