Auto-generate Instagram, Facebook & LinkedIn posts from YouTube videos with GPT-4o & Dumpling AI

Who’s it for

This template is perfect for content marketers, social media managers, and creators who want to repurpose YouTube videos into platform-specific posts without manual work. If you spend hours brainstorming captions, resizing content, or creating images for different platforms, this workflow automates the entire process from video selection to ready-to-publish posts.

What it does

The workflow takes a topic from a Google Sheet, finds the most relevant and recent YouTube video using Dumpling AI and GPT-4o, then automatically generates unique posts for Instagram, Facebook, and LinkedIn. Each post comes with a tailored AI-generated image, and all content is saved back into a Google Sheet for easy scheduling and review.

Here’s what happens step by step:

1. Picks an unsearched topic from Google Sheets
2. Searches YouTube via Dumpling AI and sorts videos
3. Uses GPT-4o to select the most relevant video
4. Extracts the video transcript using Dumpling AI
5. Generates three platform-specific posts using GPT-4o
6. Creates matching images for each post using Dumpling AI image generation
7. Saves the final Instagram, Facebook, and LinkedIn posts into a Google Sheet
8. Marks the topic as processed so it won’t repeat

How it works

1. Scheduled Trigger: Starts the workflow automatically on a set schedule
2. Google Sheets: Retrieves one unprocessed topic from the YouTube Topics sheet
3. Dumpling AI: Finds and filters YouTube videos matching the topic
4. GPT-4o: Chooses the best video and turns the transcript into three unique posts
5. Dumpling AI (Image): Generates platform-specific visuals for each post
6. Google Sheets: Saves all posts and images to the Social Media Post sheet for publishing
