About this workflow

Turn your blog into a set-and-forget content engine: every new article is instantly repurposed into channel-specific social posts with visuals, keeping your brand visible on LinkedIn, X, and Reddit without extra copywriting time. Perfect for lean marketing teams who want consistent, always-on distribution from a single source of content. How it works • Watches your blog RSS feed (or receives a single URL) and detects new articles. • Saves each post in Postgres so every article is only processed once. • Fetches the article HTML, extracts the main body content and sends it to OpenAI (GPT-4.1). • OpenAI creates platform-optimized copy: 1 LinkedIn post, 1 X/Twitter post, 1 Reddit post + image prompts. • Generates on-brand images with OpenAI and publishes everything automatically to LinkedIn, X, and Reddit. • You can also trigger it manually or via webhook whenever you want to push a specific campaign. Setup Steps • Time: around 20–40 minutes for someone familiar with n8n and the platforms. • Create a Postgres table “rssitems” with fields: guid (PRIMARY KEY), title, link, publishedat. • Add credentials in n8n for: – Postgres – OpenAI – LinkedIn OAuth2 – X/Twitter OAuth2 + OAuth1 (for media upload) – Reddit OAuth2 • In the RSS node, set your blog feed URL (for example: • In the webhook node, confirm the URL/path you want external tools or other workflows to call with a “link” field. • Run the manual trigger with one test blog URL to verify: – Article content is extracted correctly. – AI returns LinkedIn/X/Reddit posts and image prompts. – Posts and images appear correctly on all social accounts. • Once tests look good, enable the Schedule Trigger so Blog2Social AI runs automatically at your chosen interval.
