n8n RSS to Social: OpenAI Captions + Orshot Cards

Turn your RSS blog into platform-ready social posts—automatically

n8n RSS to Social: OpenAI Captions + Orshot Cards checks your RSS feed hourly, uses OpenAI to generate platform-specific captions, renders a branded Orshot social card (4:5), and publishes to Instagram, LinkedIn, X, and Facebook—while logging results and errors to Google Sheets.

What this workflow does

• Cleans and maps feed data including the article title, link, summary, category, and featured image URL.
• Uses OpenAI to generate:
  • a card headline,
  • an excerpt,
  • a topic tag,
  • captions tailored to Instagram, LinkedIn, X, and Facebook.
• Renders a branded 4:5 social card in Orshot using your selected Orshot Studio template, populated with the article image and generated text.
• Publishes via Orshot if the card renders successfully, attaching the image and the correct platform caption for each network.
• Logs publishing status (or errors) and the platform post URLs to Google Sheets.
