Automatically create and publish ready-to-post social media news updates — all powered by AI. This workflow turns any RSS feed into professional, branded posts, complete with visuals and captions. Use cases include automating news updates, sharing industry insights, or maintaining an active social presence without manual work. Good to know Fully automated end-to-end publishing — from RSS feed to social post Uses JsonCut for dynamic image composition (backgrounds, text overlays, logos) Publishes directly to Instagram (or other channels) via Blotato Utilizes OpenAI GPT-5 for post text and image prompt generation Polling mechanism checks job status every 3 seconds Setup time: under 10 minutes once credentials are in place How it works The RSS Trigger monitors any RSS feed for new content. OpenAI GPT-5 rewrites the headline and creates a short, social-friendly post caption. An AI image prompt is generated to match the article’s topic and mood. JsonCut combines the background, logo, and headline text into a branded image. Once the image is ready, Blotato uploads and publishes the post directly to Instagram (or other connected platforms). The process runs completely automatically — no human input required after setup. How to use Import the workflow into your n8n instance. Configure your RSS feed URL(s).
