This is a fully automated viral content repurposing system designed for creators, agencies, and brands who want to grow on Instagram and Pinterest without manual work.
Your automation runs daily, finds viral posts, rewrites the content using OpenAI, recreates the video with Creatomate, and finally schedules it directly to social platforms through Postiz — all on autopilot.
This workflow is built entirely in n8n, using Apify, OpenAI, Creatomate, and Postiz APIs.

WHAT THIS AUTOMATION DOES (STEP-BY-STEP)

1. Daily Trigger

A daily timer in n8n automatically starts the entire workflow every 24 hours.
(No manual action needed.)

2. Scrape Viral Instagram and Pinterest Videos (Apify)

The system sends a POST request to Apify's Instagram and Pinterest  Scraper to collect real trending Instagram posts.
It extracts:

• Video URLs

• Captions

• Like counts

• Metadata
  

Then the automation waits 90 seconds while Apify generates the data.

3. Fetch & Split Result Items

The workflow fetches the Apify dataset results and splits each Instagram post into individual items for filtering.

4. VIRAL FILTER – Only Pick Videos with 50,000+ Likes

An n8n IF filter ensures only viral-level posts (50k+ likes) are selected.
This guarantees high-performing content every time.

5. OpenAI Rewrites the Script

OpenAI GPT-4o rewrites the post into a fresh, original 15-second viral script.
It also explains WHY this type of content goes viral.
The automation parses the JSON response and prepares:

• New rewritten script

• Viral reasons

• Original caption

• Original video URL
  

6. Creatomate Auto-Generates a New Video

Using the rewritten script, Creatomate automatically generates a new, animated, branded video based on your template.
The automation waits for the render, checks the render status, and retrieves the final video URL.

7. Prepare Post Content (Video + Hashtags)

The script prepares:

• Final video

• Caption

• Hashtags (#viral #fyp #motivation #success)
  

8. Auto-Publish via Postiz

The final step uploads the video and caption automatically to Postiz for posting to:

• Instagram

• TikTok

• Facebook

• LinkedIn

• YouTube Shorts
  

• pinterest

This system can run daily, posting content for you automatically.
