Transform Video Transcripts into Multi-Platform Social Media Posts with Groq AI

Overview

This workflow automates the process of turning your video transcripts into platform-specific social media posts using AI. It reads any uploaded transcript file, analyzes the text, and automatically generates full-length, engaging posts with image prompts for Facebook, LinkedIn, Instagram, Reddit, and WhatsApp.

Perfect for creators, marketers, and automation builders who want to repurpose long-form content into viral posts, all in one click.

How it Works

The Manual Trigger starts the workflow.

The Read Binary File node imports your video transcript (TXT format). The Move Binary Data and Set nodes convert it into a text string for processing. The AI Agent (LangChain) powered by Groq AI analyzes the transcript and generates human-like social media posts with realistic image prompts. The Function Node parses and structures the output by platform. The Google Sheets Node automatically saves all content — ready for scheduling or publishing. The SerpAPI Integration enhances contextual awareness by referencing real-time search trends.

Set Up Steps

Setting up this workflow typically takes 5–10 minutes. Connect your Google Sheets account (OAuth2). Connect your Groq AI and SerpAPI credentials. Upload your transcript file (e.g., from YouTube or podcast). Run the workflow to instantly generate platform-specific posts and prompts. View all results automatically saved in Google Sheets. Detailed instructions are included as sticky notes inside the workflow.
