Automate YouTube to X Posts with GPT-3.5 in n8n

Turn new YouTube uploads into automated X (Twitter) posts every 30 minutes

This n8n workflow automatically checks a specified YouTube channel for newly published videos and uses OpenAI ChatGPT (GPT-3.5) to generate a short, link-ready X post—then publishes it to your connected X account. No manual copy/paste required.

What this workflow does

• Runs on a 30-minute schedule using an n8n Schedule Trigger.
• Fetches the latest YouTube video from your chosen YouTube Channel ID that was published within the last 30 minutes.
• Feeds video content to OpenAI ChatGPT, sending the video title, description, and URL to generate an engaging X post limited to 140 characters.
• Publishes the generated post to X (Twitter) using your connected X (Twitter) OAuth2 credentials, ensuring the workflow has permission to create posts on your account.
