🎥 YouTube → LinkedIn Poster – AI-Powered n8n Workflow
# 🎥 YouTube to LinkedIn Poster – n8n Workflow Template
Turn any YouTube video into a high-performing LinkedIn post — automatically.
This AI-powered n8n workflow takes a YouTube video ID, fetches the transcript using SearchAPI.io, and transforms it into a professional, engaging LinkedIn post using OpenAI (via OpenRouter). Customize the writing style, automate your content repurposing, and scale your thought leadership.

## 🚀 How I Used It in My MicroSaaS
I used this exact workflow as the backend for a lead magnet SaaS tool that converts YouTube videos into LinkedIn posts. With a simple UI and webhook, users paste a video link, choose a tone, and instantly receive a high-quality post they can copy and share. It increased lead generation and engagement while costing nothing in backend dev. Check it out here: https://trafficabc.com/youtube-to-linkedin-poster-with-ui/
The best part? I only used:
- n8n + Webhook
- OpenRouter API
- A WordPress front-end with credit gating
