Automate Daily Instagram News Carousels with n8n, Claude & Gemini

This n8n workflow automatically pulls trending news from Google News, uses Anthropic Claude to write your Instagram caption and slide plan, generates matching images with Google Gemini, uploads them to Amazon S3, and publishes a single post or a carousel to Instagram via the Facebook Graph API—running every 24 hours.

What this workflow does

• Runs on a 24-hour schedule to publish fresh content consistently.
• Rotates through predefined topic-based Google News RSS feeds and fetches the top headlines.
• Builds a short context from the top three articles and sends it to Anthropic Claude to select one headline and generate:
  • the Instagram caption
  • hashtags
  • a slide plan (single image or carousel)
• Normalizes Claude’s output, enforces the configured post type, and converts each slide into a branded image prompt.
• Generates images with Google Gemini, optionally composites a logo, and uploads the image files to Amazon S3 to create public image URLs.
• Publishes to Instagram by creating an Instagram media container (single image or carousel) using the Facebook Graph API, polling until finished, then publishing to your connected Instagram business account.

Use cases

• Run a news-themed Instagram account with daily carousels that stay aligned to specific topics.
• For SaaS operators, maintain a hands-off content pipeline that combines RSS discovery + AI writing + image generation.
• Automation engineers can use this as a template for AI-assisted social publishing workflows in n8n.
