Auto-generate blog and social thumbnails with n8n and Ideogram
setuproll@setuproll83.0Overall score
An n8n automation that watches your CMS for new posts, uses GPT-5 to write a tight image prompt, then renders a thumbnail with Ideogram (which nails legible in-image text) and uploads it back. For bloggers and content teams who want on-brand cover art generated the moment a draft is published.
