AI Agent for Instagram Trend Content Generation & Publishing

Unlock Automated & Engaging Instagram Content with this AI Agent

This n8n workflow acts as an AI Agent designed to keep your Instagram presence vibrant and up-to-date with minimal effort. It starts by scraping top trending posts for specified hashtags (e.g., #blender3d, #isometric) via RapidAPI. The Agent then uses OpenAI's GPT-4o-mini to analyze the visual content of these trending images and generate compelling, Instagram-ready captions. Leveraging Replicate's Flux AI model, it creates entirely new, unique images inspired by the analyzed trends and descriptions. Before posting, it checks a PostgreSQL database to avoid duplicate content. Finally, it seamlessly publishes the AI-generated image and caption to your Instagram Business account and notifies you via Telegram about the post status or any issues.

This AI Agent's abilities include:

• Trend Discovery: Scans Instagram for top posts based on your chosen hashtags.
• AI Image Analysis: Understands key visual elements of trending images using OpenAI.
• AI Caption Generation: Crafts engaging Instagram captions with relevant hashtags using OpenAI.
• AI Image Generation: Produces novel images based on trend analysis using Replicate (Flux AI).
• Automated Publishing: Posts content directly to your Instagram Business account.
• Status Monitoring & Notification: Keeps you updated via Telegram.
