AI Content Repurposing Pipeline for n8n GUI

Transform fresh blog posts and YouTube videos into a complete social media campaign automatically.

This workflow watches RSS feeds from your favorite sources — blogs, Substack newsletters, Reddit, and YouTube channels — and turns each new piece of content into a ready-to-post package:

- X Thread – a viral, multi-tweet thread (5 tweets)

- LinkedIn Post – an engaging hook-driven post with hashtags

- Newsletter Blurb – a two-sentence curiosity-driven teaser

How it works

1. Ingest – Pulls the latest items from multiple RSS feeds in parallel.

2. Extract – Fetches the full article HTML and strips it to clean text (or pulls the YouTube transcript for videos).

3. Normalize & Validate – Standardizes content, timestamps each item, and drops anything too short to work with.

4. Generate – Sends each article to GPT-4o-mini with platform-specific prompts, producing a thread, a LinkedIn post, and a newsletter teaser.

5. Parse – Cleans and structures the AI output into validated JSON per platform.

6. Deliver – Returns everything in a single, ready-to-consume response.
